# Introduction

This is the organisation wiki for the **openQA Project**.

The source code is hosted in the [os-autoinst github project](http://github.com/os-autoinst/), especially [openQA itself](http://github.com/os-autoinst/openQA) and the main backend [os-autoinst](http://github.com/os-autoinst/os-autoinst)

If you are interested in the tests for SUSE/openSUSE products take a look into the [openqatests](https://progress.opensuse.org/projects/openqatests) project.

If you are looking for entry level issues to contribute to please look into the section [[Wiki#Where-to-contribute|Where to contribute]]

# Organisational

## ticket workflow

The following ticket statuses are used together and their meaning is explained:

* *New*: No one has worked on the ticket (e.g. the ticket has not been properly refined) or no one is feeling responsible for the work on this ticket.

* *Workable*: The ticket has been refined and is ready to be picked.

* *In Progress*: Assignee is actively working on the ticket.

* *Resolved*: The complete work on this issue is done and the according issue is supposed to be fixed as observed (Should be updated together with a link to a merged pull request or also a link to an production openQA showing the effect)

* *Feedback*: Further work on the ticket needs clarification of open points within the ticket or is awaiting feedback from others or other systems (e.g. automated tests) to proceed. Sometimes also used to ask Assignee about progress on inactivity.

* *Blocked*: Further work on the ticket is blocked by some external dependency (e.g. bugs, not implemented features). There should be a link to another ticket, bug, trello card, etc. where it can be seen what the ticket is blocked by.

* *Rejected*: The issue is considered invalid, should not be done, is considered out of scope.

* *Closed*: As this can be set only by administrators it is suggested to not use this status.

It is good practice to update the status together with a comment about it, e.g. a link to a pull request or a reason for reject.

## ticket categories

* *Concrete Bugs*: Regressions, crashes, error messages

* *Feature requests*: Ideas or wishes for extension, enhancement, improvement

* *Organisational*: Organisational tasks within the project(s), not directly code related

* *Support*: Support of users, usage problems, questions

Please avoid the use of other, deprecated categories

Suggestion by *okurz*: I recommend to avoid the word "bug" in our categories because of the usual "is it a bug or a feature" struggle. Instead I suggest to strictly define "Regressions & Crashes" to clearly separate "it used to work in before" from "this was never part of requirements" for Features. Any ticket of this category also means that our project processes missed something so we have points for improvements, e.g. extend things to look out for in code review.

## Epics and Sagas

[epic]s and [saga]s belong to the "coordination" tracker, project contributors are not required to follow this convention but the tracker may be changed automagically in the future: http://mailman.suse.de/mailman/private/qa-sle/2020-October/002722.html 

## ticket templates

You can use these templates to fill in tickets and further improve them with more detail over time. Copy the code block, paste it into a new issue, replace every block marked with "<…>" with your content or delete if not appropriate.

## Further decision steps working on test issues

Test issues could be one of the following sources. Feel free to use the following template in tickets as well

```

## Problem

* **H1** The product has changed

 * **H1.1** product changed slightly but in an acceptable way without the need for communication with DEV+RM --> adapt test

 * **H1.2** product changed slightly but in an acceptable way found after feedback from RM --> adapt test

 * **H1.3** product changed significantly --> after approval by RM adapt test

* **H2** Fails because of changes in test setup

 * **H2.1** Our test hardware equipment behaves different

 * **H2.2** The network behaves different

* **H3** Fails because of changes in test infrastructure software, e.g. os-autoinst, openQA

* **H4** Fails because of changes in test management configuration, e.g. openQA database settings

* **H5** Fails because of changes in the test software itself (the test plan in source code as well as needles)

* **H6** Sporadic issue, i.e. the root problem is already hidden in the system for a long time but does not show symptoms every time

```

This is following the [scientific method](https://en.wikipedia.org/wiki/Scientific_method). It is suggested to use the characters *H* (hypothesis), *E* (experiment), *O* (observation), e.g. like this

```

* **H3** Fails because of changes in test infrastructure software, e.g. os-autoinst, openQA

  * **H3.1** **REJECTED** Fails because of changes in openQA itself

    * **E3.1-1** (First experiment for hypothesis 3.1) test on an openQA server with the openQA version of "last good"

      * **O3.1-1-1** (First observation for first experiment for hypothesis 3) the test failed in the same way, reject *H3.1*

```

## Additional details needed for non-qemu issues

As the automatic integration tests of os-autoinst and openQA are based on qemu virtualization, for any non-qemu related requests please provide detailed manual reproduction steps, otherwise it is unlikely that any issue or feature request can be implemented.

## pull request handling on github

As a reviewer of pull requests on github for all related repositories, e.g. https://github.com/os-autoinst/os-autoinst-distri-opensuse/pulls, apply labels in case PRs are open for a longer time and can not be merged so that we keep our backlog clean and know why PRs are blocked.

* **notready**: Triaged as not ready yet for merging, no (immediate) reaction by the reviewee, e.g. when tests are missing, other scenarios break, only tested for one of SLE/TW

* **wip**: Marked by the reviewee itself as "[WIP]" or "[DO-NOT-MERGE]" or similar

* **question**: Questions to the reviewee, not answered yet

## Where to contribute?

If you want to help openQA development you can take a look into the existing [issues](https://progress.opensuse.org/projects/openqav3/issues).

You can start with

* [entrance level issues](https://progress.opensuse.org/projects/openqav3/search?q=entrance+level+issue&open_issues=1)

* issues tagged as [easy](https://progress.opensuse.org/projects/openqav3/issues?utf8=%E2%9C%93&set_filter=1&sort=id%3Adesc&f%5B%5D=status_id&op%5Bstatus_id%5D=o&f%5B%5D=issue_tags&op%5Bissue_tags%5D=%3D&v%5Bissue_tags%5D%5B%5D=easy&f%5B%5D=&c%5B%5D=subject&c%5B%5D=project&c%5B%5D=status&c%5B%5D=assigned_to&c%5B%5D=fixed_version&c%5B%5D=is_private&c%5B%5D=due_date&c%5B%5D=relations&group_by=&t%5B%5D=)

* issues tagged as [beginner](https://progress.opensuse.org/projects/openqav3/issues?utf8=%E2%9C%93&set_filter=1&sort=id%3Adesc&f%5B%5D=status_id&op%5Bstatus_id%5D=o&f%5B%5D=issue_tags&op%5Bissue_tags%5D=%3D&v%5Bissue_tags%5D%5B%5D=beginner&f%5B%5D=&c%5B%5D=subject&c%5B%5D=project&c%5B%5D=status&c%5B%5D=assigned_to&c%5B%5D=fixed_version&c%5B%5D=is_private&c%5B%5D=due_date&c%5B%5D=relations&group_by=&t%5B%5D=) - not necessarily "easy" but more suitable for someone coming to a project with little or no domain specific knowledge

* ideas from #65271

There are also some "always valid" tasks to be working on:

* *improve test coverage*:

 * *user story*: As openqa backend as well as test developer I want better test coverage of our projects to reduce technical debt

 * *acceptance criteria*: test coverage is significantly higher than before

 * *suggestions*: check current coverage in each individual project (os-autoinst/openQA/os-autoinst-distri-opensuse) and add tests as necessary

# Use cases

The following use cases 1-6 have been defined within a SUSE workshop (others have been defined later) to clarify how different actors work with openQA. Some of them are covered already within openQA quite well, some others are stated as motivation for further feature development.

## Use case 1

**User:** QA-Project Managment

**primary actor:** QA Project Manager, QA Team Leads

**stakeholder:** Directors, VP

**trigger:** product milestones, providing a daily status

**user story:** „As a QA project manager I want to check on a daily basis the „openQA Dashboard“ to get a summary/an overall status of the „reviewers results“ in order to take the right actions and prioritize tasks in QA accordingly.“

# Thoughts about categorizing test results, issues, states within openQA

by okurz

When reviewing test results it is important to distinguish between different causes of "failed tests"

## Nomenclature

### Test status categories

A common definition about the status of a test regarding the product it tests: "false|true positive|negative" as described on https://en.wikipedia.org/wiki/False_positives_and_false_negatives. "positive|negative" describes the outcome of a test ("positive": test signals presence of issue; "negative": no signal) whereas "false|true" describes the conclusion of the test regarding the presence of issues in the SUT or product in our case ("true": correct reporting; "false": incorrect reporting), e.g. "true negative", test successful, no issues detected and there are no issues, product is working as expected by customer. Another example: Think of testing as of a fire alarm. An alarm (event detector) should only go off (be "positive") *if* there is a fire (event to detect) --> "true positive" whereas *if* there is *no* fire there should be *no* alarm --> "true negative".

Another common but potentially ambiguous categorization:

* *broken*: the test is not behaving as expected (Ambiguity: "as expected" by whom?) --> commonly a "false positive", can also be "false negative" but hard to detect

* *failing*: the test is behaving as expected, but the test output is a fail --> "true positive"

* *working*: the test is behaving as expected (with no comment regarding the result, though some might ambiguously imply 'result is negative')

* *passing*: the test is behaving as expected, but the result is a success --> "true negative"

If in doubt declare a test as "broken". We should review the test and examine if it is behaving as expected.

Be careful about "positive/negative" as some might also use "positive" to incorrectly denote a passing test (and "negative" for failing test) as an indicator of "working product" not an indicator about "issue present". If you argue what is "used in common speech" think about how "false positive" is used as in "false alarm" --> "positive" == "alarm raised", also see https://narainko.wordpress.com/2012/08/26/understanding-false-positive-and-false-negative/

### Priorization of work regarding categories

In this sense development+QA want to accomplish a "true negative" state whenever possible (no issues present, therefore none detected). As QA and test developers we want to prevent "false positives" ("false alarms" declaring a product as broken when it is not but the test failed for other reasons), also known as "type I error" and "false negatives" (a product issue is not catched by tests and might "slip through" QA and at worst is only found by an external outside customer) also known as "type II error". Also see https://en.wikipedia.org/wiki/Type_I_and_type_II_errors. In the context of openQA and system testing paired with screen matching a "false positive" is much more likely as the tests are very susceptible to subtle variations and changes even if they should be accepted. So when in doubt, create an issue in progress, look at it again, and find that it was a false alarm, rather than wasting more peoples time with INVALID bug reports by believing the product to be broken when it isn't. To quote Richard Brown: "I […] believe this is the route to ongoing improvement - if we have tests which produce such false alarms, then that is a clear indicator that the test needs to be reworked to be less ambiguous, and that IS our job as openQA developers to deal with".

## Further categorization of statuses, issues and such in testing, especially automatic tests

By okurz

This categorization scheme is meant to help in communication in either written or spoken discussions being simple, concise, easy to remember while unambiguous in every case.

While used for naming it should also be used as a decision tree and can be followed from the top following each branch.

### Categorization scheme

To keep it simple I will try to go in steps of deciding if a potential issue is of one of two categories in every step (maybe three) and go further down from there. The degree of further detailing is not limited, i.e. it can be further extended. Naming scheme should follow arabic number (for two levels just 1 and 2) counting schemes added from the right for every additional level of decision step and detail without any separation between the digits, e.g. "1111" for the first type in every level of detail up to level four. Also, I am thinking of giving the fully written form phonetic name to unambiguously identify each on every level as long as not more individual levels are necessary. The alphabet should be reserved for higher levels and higher priority types.

Every leaf of the tree must have an action assigned to it.

1 **failed** (ZULU)

11 new (passed->failed) (YANKEE)

111 product issue ("true positive") (WHISKEY)

1111 unfiled issue (SIERRA)

11111 hard issue (openqa *fail*) (KILO)

111121 critical / potential ship stopper (INDIA) --> immediately file bug report with "ship_stopper?" flag; opt. inform RM directly

111122 non-critical hard issue (HOTEL) --> file bug report

11112 soft issue (openqa *softfail* on job level, not on module level) (JULIETT) --> file bug report on failing test module

1112 bugzilla bug exists (ROMEO)

11121 bug was known to openqa / openqa developer --> cross-reference (bug->test, test->bug) AND raise review process issue, improve openqa process

11122 bug was filed by other sources (e.g. beta-tester) --> cross-reference (bug->test, test->bug)

112 test issue ("false positive") (VICTOR)

1121 progress issue exists (QUEBEC) --> cross-reference (issue->test, test->issue)

1122 unfiled test issue (PAPA)

11221 easy to do w/o progress issue

112211 need needles update --> re-needle if sure, TODO how to notify?

112212 pot. flaky, timeout

1122121 retrigger yields PASS --> comment in progress about flaky issue fixed

1122122 reproducible on retrigger --> file progress issue

11222 needs progress issue filed --> file progress issue

12 existing / still failing (failed->failed) (XRAY)

121 product issue (UNIFORM)

1211 unfiled issue (OSCAR) --> file bug report AND raise review process issue (why has it not been found and filed?)

1212 bugzilla bug exists (NOVEMBER) --> ensure cross-reference, also see rules for 1112 ROMEO

122 test issue (TANGO)

1221 progress issue exists (MIKE) --> monitor, if persisting reprioritize test development work

1222 needs progress issue filed (LIMA) --> file progress issue AND raise review process issue, see 1211 OSCAR

2 **passed** (ALFA)

21 stable (passed->passed) (BRAVO)

211 existing "true negative" (DELTA) --> monitor, maybe can be made stricter

212 existing "false negative" (ECHO) --> needs test improvement

22 fixed (failed->passed) (CHARLIE)

222 fixed "true negative" (FOXTROTT) --> TODO split monitor, see 211 DELTA

2221 was test issue --> close progress issue

2222 was product issue

22221 no bug report exists --> raise review process issue (why was it not filed?)

22222 bug report exists

222221 was marked as RESOLVED FIXED

221 fixed but "false negative" (GOLF) --> potentially revert test fix, also see 212 ECHO

Priority from high to low: INDIA->OSCAR->HOTEL->JULIETT->…

# Proposals for uses of labels

With [Show bug or label icon on overview if labeled (gh#550)](https://github.com/os-autoinst/openQA/pull/550) it is possible to add custom labels just by writing them. Nevertheless, a convention should be found for a common benefit. <del>Beware that labels are also automatically carried over with (Carry over labels from previous jobs in same scenario if still failing [gh#564])(https://github.com/os-autoinst/openQA/pull/564) which might make consistent test failures less visible when reviewers only look for test results without labels or bugrefs.</del> Labels are not anymore automatically carried over ([gh#1071](https://github.com/os-autoinst/openQA/pull/1071)).

List of proposed labels with their meaning and where they could be applied.

* ***`fixed_<build_ref>`***: If a test failure is already fixed in a more recent build and no bug reference is known, use this label together with a reference to a more recent passed test run in the same scenario. Useful for reviewing older builds. Example (https://openqa.suse.de/tests/382518#comments):

```

label:fixed_Build1501

t#382919

```

* ***`needles_added`***: In case needles were missing for test changes or expected product changes caused needle matching to fail, use this label with a reference to the test PR or a proper reasoning why the needles were missing and how you added them. Example (https://openqa.suse.de/tests/388521#comments):

```

label:needles_added

needles for https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/1353 were missing, added by jpupava in the meantime.

```

# s390x Test Organisation

See the following picture for a graphical overview of the current s390x test infrastructure at SUSE:

![SUSE s390x test infrastructure](qa_sle_openqa_s390x_test_infrastructure.jpg)

## Upgrades

### on z/VM 

#### special Requirements

Due to the lack of proper use of hdd-images on zVM, we need to workaround this with having a dedicated worker_class aka a dedicated Host where we run two jobs with START_AFTER_TEST,

the first one which installs the basesystem we want to have upgraded and a second one which is doing the actually upgrade (e.g migration_offline_sle12sp2_zVM_preparation and migration_offline_sle12sp2_zVM)

Since we encountered issues with randomly other preparation jobs are started in between there, we need to ensure that we have one complete chain for all migration jobs running on one worker, that means for example:

1. migration_offline_sle12sp2_zVM_preparation 

1. migration_offline_sle12sp2_zVM (START_AFTER_TEST=#1) 

1. migration_offline_sle12sp2_allpatterns_zVM_preparation (START_AFTER_TEST=#2) 

1. migration_offline_sle12sp2_allpatterns_zVM 

1. ...

This scheme ensures that all actual Upgrade jobs are finding the prepared system and are able to upgrade it

### on z/KVM

No special requirements anymore, see details in #18016

## Automated z/VM LPAR installation with openQA using qnipl

There is an ongoing effort to automate the LPAR creation and installation on z/VM. A first idea resulted in the creation of [qnipl](https://github.com/openSUSE/dracut-qnipl). `qnipl` enables one to boot a very slim initramfs from a shared medium (e.g. shared SCSI-disks) and supply it with the needed parameters to chainload a "normal SLES installation" using kexec.

This method is required for z/VM because snipl (Simple network initial program loader) can only load/boot LPARs from specific disks, not network resources.

### Setup

1. Get a shared disk for all your LPARs

  * Normally this can easily done by infra/gschlotter

  * Disks needs to be connected to all guests which should be able to network-boot

1. Boot a fully installed SLES on one of the LPARs to start preparing the shared-disk

1. Put a DOS partition table on the disk and create one single, large partition on there

1. Put a FS on there. Our first test was on ext2 and it worked flawlessly in our attempts

1. Install `zipl` (The s390x bootloader from IBM) on this partition

  * A simple and sufficient config can be found in [poo#33682](https://progress.opensuse.org/issues/33682)

1. clone [`qnipl`](https://github.com/nicksinger/dracut-qnipl) to your dracut modules (e.g. /usr/lib/dracut/modules.d/95qnipl)

1. Include the module named `qnipl` to your dracut modules for initramfs generation

  * e.g. in /etc/dracut.conf.d/99-qnipl.conf add: `add_dracutmodules+=qnipl`

1. Generate your initramfs (e.g. `dracut -f -a "url-lib qnipl" --no-hostonly-cmdline /tmp/custom_initramfs`)

  * Put the initramfs next to your kernel binary on the partition you want to prepare

1. From now on you can use `snipl` to boot any LPAR connected with this shared disk from network

  * example: `snipl -f ./snipl.conf -s P0069A27-LP3 -A fa00 --wwpn_scsiload 500507630713d3b3 --lun_scsiload 4001401100000000 --ossparms_scsiload "install=http://openqa.suse.de/assets/repo/SLE-15-Installer-DVD-s390x-Build533.2-Media1 hostip=10.161.159.3/20 gateway=10.161.159.254 Nameserver=10.160.0.1 Domain=suse.de ssh=1 regurl=http://all-533.2.proxy.scc.suse.de"`

  * `--ossparms_scsiload` is then evaluated and used by `qnipl` to kexec into the installer with the (for the installer) needed parameters

### Further details

Further details can also be found in the [github repo](https://github.com/openSUSE/dracut-qnipl/blob/master/README.md). Pull requests, questions and ideas always welcome!

# Infrastructure setup for o3 (openqa.opensuse.org) and osd (openqa.suse.de)

Both o3 and osd are hosted in SUSE data centers, mostly Nuremberg, Germany, and Prague, Czech Republic.

Interesting monitoring link referring to both (SUSE internal):

* https://bs-monitor.nue.suse.com:3000/d/paTR0FXnz/temperature-and-humidity-in-nuremberg-server-rooms?orgId=1&viewPanel=4&from=now-24h&to=now (SUSE internal) for climate control in SUSE Nuremberg Maxtorhof hosting, also http://srv2mgmt:3000/ with "monitor:monitor"

## o3 (openqa.opensuse.org)

o3 consists of a VM running the web UI and physical worker machines. The VM for o3 has netapp backed storage on rotating disk so less performant than SSD but cheaper. So eventually we might have the possibility to use SSD based storage. Currently there are four virtual storage devices provided to o3 totalling to 10 TB.

The o3 infrastructure is in detail described on https://github.com/os-autoinst/sync-and-trigger/blob/main/openqa-opensuse.md

### Accessing the o3 infrastructure

The o3 webui host as well the workers within the o3 infrastructure can be accessed over ssh by using `ssh -p 2213 gate.opensuse.org`. Ask one of the existing admins within https://app.element.io/#/room/#openqa:opensuse.org or irc://irc.libera.chat/opensuse-factory (so that I know you can be reached over those channels when people have questions to you what you did with the ssh access) to put your ssh key on the o3 webui host to be able to login. 

To give access for a new user an existing admin can do the following:

```

sudo useradd -G users,trusted --create-home $user

echo "$ssh_key_from_user" | sudo tee -a /home/$user/.ssh/authorized_keys

```

#### SSH configuration

To easily access all hosts behind the jump host you can use the following config for your ssh client (`~/.ssh/config`):

```

Host ariel

  HostName gate.opensuse.org

  Port 2213

# Note that %h as understood by -W needs the real host, aliases won't work:

# kex_exchange_identification: Connection closed by remote host

# Connection closed by UNKNOWN port 65535`

Host *.opensuse.org

  ProxyCommand ssh -q -A -x ariel -W %h:%p

```

**A word of warning:** be aware that this enables agent-forwarding to at least the jumphost. Please read up for yourself if and how bad you consider the security implications of doing so.

The workers can only be accessed from "ariel", not directly. One can use password authentication on the workers using the root account. Ask existing admins for the root password. It is suggested that you use key-based authentication. For this put your ssh keys on all the workers, e.g. using the above configuration and `ssh-copy-id`.

**Notice:** Some machines are connected to the o3 openQA host from other networks and might need different ways of access, at time of writing:

* Remote (owner: @ggardet_arm):

 * ip-10-0-0-58

 * oss-cobbler-03

 * siodtw01 (for tests on Raspberry Pi 2,3,4)

### Manual command execution on o3 workers

To execute commands manually on all workers within the o3 infrastructure one can do for example the following:

```

for i in aarch64 openqaworker1 openqaworker4 openqaworker7 openqaworker19 openqaworker20 power8 qa-power8-3 rebel; do echo $i && ssh root@$i "zypper -n dup && reboot" ; done

```

```

for i in aarch64 openqaworker1 openqaworker4 openqaworker7 openqaworker19 openqaworker20 power8 qa-power8-3 rebel; do echo $i && ssh root@$i " echo 'ssh-rsa … …' >> /root/.ssh/authorized_keys " ; done

```

mind the correct list of machines.

Formerly for true transactional servers we used:

```

for i in $hosts; do echo $i && ssh root@$i "(transactional-update -n dup || zypper -n dup) && reboot" ; done

```

### Automatic update of o3

o3 is automatically deployed on a daily base, that includes both the webUI host as well as the workers.

#### Automatic update of o3 webUI host

openqa.opensuse.org applies continuous updates of openQA related packages, conducts nightly updates of system packages and reboots automatically as required, see

http://open.qa/docs/#_automatic_system_upgrades_and_reboots_of_openqa_hosts

for details

#### Recurring automatic update of openQA workers

Same as the o3 webUI all o3 workers all apply continuous updates of openQA related packages. Additionally most apply a daily automatic system update and are "Transactional Servers" running openSUSE Leap. power8 is non-transactional with a weekly update of the system every Sunday.

This was for a number of reasons including:

* Getting all the machines consistent after a few years of drift

* Making it easier to keep them consistent by leveraging a read only root filesystem

* Guaranteeing rollbackability by using transactional updates

This was done by rbrown also to fulfill the prerequisite to getting them viable for multi-machine testing

These systems currently patch themselves and reboot automatically in the default maintenance window of 0330-0500 CET/CEST.

On problems this could be changed in the following way:

* Edit the maintenance window in /etc/rebootmgr.conf

* Disable the automatic reboot by "systemctl disable rebootmgr.service"

* Disable the automatic patching by "systemctl disable transactional-update.timer"

EDIT: 2022-07-11: All o3 machines are effectively not "transactional-workers" anymore as openqa-continuous-update.service is doing a complete `zypper dup` every couple of minutes. With `rebootmgr` triggered for reboot still automatic nightly reboots happen as necessary. See #111989 for details

SUSE employees have access to the bootmenu for the openQA worker machines, e.g. openqaworker1 and openqaworker4 via openqaworker1- ipmi.suse.de and openqaworker4-ipmi.suse.de which are both connected to the r&d network. For imagetester one would need to go through SUSE-IT in an unlikely event of a boot-preventing update. "snapper rollback" can be executed from a booted, functionally operative machine which one can ssh into.

For manual investigation https://github.com/kubic-project/microos-toolbox can be helpful

#### Rollback of updates

Updates on workers can be rolled back using `transactional-update` affecting the transactional workers (others are likely not updated that often):

```

for i in aarch64 openqaworker1 openqaworker4 openqaworker7 power8 imagetester rebel; do echo $i && ssh root@$i "transactional-update rollback last && reboot"; done

```

Updates on the central webUI host openqa.opensuse.org can be rolled back by using either older variants of packages that receive maintenance updates or using the locally cached packages in e.g. /var/cache/zypp/packages/devel_openQA/noarch using `zypper in --oldpackage`, similar to https://github.com/os-autoinst/openQA/blob/master/script/openqa-rollback#L39

#### Debugging qemu SUTs in openqa.opensuse.org

SUT: System Under Test

os-autoinst starts qemu with network type that doesn't allow access from the outside, so ssh is not possible. But, qemu is started with a VNC channel available from the host (the openQA-worker).

Running vncviewer inside a headless server is useless, but it is possible to use gate.opensuse.org as a jump host and SSH port forwarding to start vncviewer client from your desktop environment and connect to the VNC channel of the qemu SUT.

```

ssh -p 2213 -L LOCAL_PORT:WORKER_HOSTNAME:QEMU_VNC_PORT USERNAME@gate.opensuse.org

```

For example, if user **bernhard**, wants to connect to openqaworker7:11, and wants to use local port **43043**

Being the IP of openqaworker7 **192.168.112.12**

And the VNC channel port of openqa-worker@11 **6001** (5990 + 11)

##### 1. Create SSH tunnel with port forwarding

* on laptop shell 1: ssh -p 2213 -L 43043:192.168.112.12:6001 bernhard@gate.opensuse.org

* Keep shell open to keep the tunnel open and the port forwarding

##### 2. Open vncviewer

* on laptop shell 2: vncviewer -Shared localhost:43043

* `-shared` is needed to not kick the VNC connection of os-autoinst. If it is kicked, the job will terminate and the qemu process will be killed.

### AArch64 specific configurations on o3

On o3, the aarch64 workers need additional configuration.

#### Setup HugePages

You need to setup HugePages support to improve performances with qemu VM and to match current aarch64 `MACHINE` configuration.

For the D05 machine, the configuration is: `40` pages with a size of `1G`.

If there are some permissions issues on `/dev/hugepages/`, check https://progress.opensuse.org/issues/53234

Allow containers to access cache service (`systemctl edit openqa-worker-cacheservice.service`):

```

# /etc/systemd/system/openqa-worker-cacheservice.service.d/override.conf

[Service]

Environment="MOJO_LISTEN=http://0.0.0.0:9530"

```

The s390 workers for openQA are running within podman containers on openqaworker1.

The containers are started using systemd but the unit files are specific to the containers and will end up in a restart-loop if this fact is ignored. Whenever the containers are recreated, the systemd files have to be recreated.

The containers are started like this (for i=101…104):

```

i=101

podman run -d -h openqaworker1_container --name openqaworker1_container_$i -p $(python3 -c"p=${i}*10+20003;print(f'{p}:{p}')") -e OPENQA_WORKER_INSTANCE=$i -v /opt/s390x_rebel_replacement:/etc/openqa -v /var/lib/openqa/share:/var/lib/openqa/share -v /var/lib/openqa/cache:/var/lib/openqa/cache registry.opensuse.org/devel/openqa/containers15.4/openqa_worker_os_autoinst_distri_opensuse:latest

(cd /etc/systemd/system/; podman generate systemd -f -n --new openqaworker1_container_$i --restart-policy always)

systemctl daemon-reload

systemctl enable container-openqaworker1_container_$i

```

To restart and permanently enable all workers at once:

```

for i in {101..104} ; do systemctl stop container-openqaworker1_container_$i ; done

podman rm -f openqaworker1_container_{101..104}

for i in {101..104} ; do podman run -d -h openqaworker1_container --name openqaworker1_container_$i -p $(python3 -c"p=${i}*10+20003;print(f'{p}:{p}')") -e OPENQA_WORKER_INSTANCE=$i -v /opt/s390x_rebel_replacement:/etc/openqa -v /var/lib/openqa/share:/var/lib/openqa/share -v /var/lib/openqa/cache:/var/lib/openqa/cache registry.opensuse.org/devel/openqa/containers15.4/openqa_worker_os_autoinst_distri_opensuse:latest ; done

for i in {101..104} ; do (cd /etc/systemd/system/; podman generate systemd -f -n --new openqaworker1_container_$i --restart-policy always) ; done

systemctl daemon-reload

podman rm -f openqaworker1_container_{101..104}

for i in {101..104} ; do systemctl reenable container-openqaworker1_container_$i && systemctl restart container-openqaworker1_container_$i ; done

```

Initial ticket when the setup was created: https://progress.opensuse.org/issues/97751

As alternative s390x workers can run on the host "rebel" as well. Be aware that openQA workers accessing the same s390x instances must not run in parallel so only enable one worker instance per s390x instance at a time (See https://progress.opensuse.org/issues/97658 for details).

### Monitoring

openqa.opensuse.org is monitored by SUSE over https://zabbix.suse.de/. There is a user group "Owners/O3" to which SUSE employees can be added.

There is also an internal munin instance on o3. Anyone wanting to look at the HTML pages, do this:

```

rsync -a o3:/srv/www/htdocs/munin ~/o3-munin/ 

```

(where "o3" is configured in your ssh config of course)

## Hotfixing

Applying hotfixes, e.g. patches from an os-autoinst pull requests to O3 workers can be applied like this for a pull request <pr_id>:

```

for i in openqaworker1 openqaworker4 openqaworker7 openqaworker19 imagetester rebel power8 qa-power8-3; do echo $i && ssh root@$i "(transactional-update run /bin/sh -c \"curl -sS https://patch-diff.githubusercontent.com/raw/os-autoinst/os-autoinst/pull/${pr_id}.patch | patch -p1 --directory=/usr/lib/os-autoinst\" && reboot) || curl -sS https://patch-diff.githubusercontent.com/raw/os-autoinst/os-autoinst/pull/${pr_id}.patch | patch -p1 --directory=/usr/lib/os-autoinst" ; done

```

Hotpatching on all OSD workers with the same <pr_id> as above with something like

```

sudo salt --no-color --state-output=changes -C 'G@roles:worker' cmd.run 'curl -sS https://patch-diff.githubusercontent.com/raw/os-autoinst/os-autoinst/pull/${pr_id}.patch | patch -p1 --directory=/usr/lib/os-autoinst'

```

## Mitigation of boot failure or disk issues

### Worker stuck in recovery

Check disk health and consider manual fixup of mount points, e.g.:

```

test -e /dev/md/openqa || lsblk -n | grep -v nvme | grep "/$" && mdadm --create /dev/md/openqa --level=0 --force --raid-devices=$(ls /dev/nvme?n1 | wc -l) --run /dev/nvme?n1 || mdadm --create /dev/md/openqa --level=0 --force --raid-devices=1 --run /dev/nvme0n1p3

```

## PPC specific configurations

In one case it was necessary to disable snapshots for petitboot with `nvram -p default --update-config "petitboot,snapshots?=false"` to prevent a race condition between dm_raid and btrfs trying to discover bootable devices (#68053#note-25). In another case https://bugzilla.opensuse.org/show_bug.cgi?id=1174166 caused the boot entries to be not properly discovered and it was necessary to prevent grub from trying to update the according sections (#68053#note-31).

## Moving worker from osd to o3

* Ensure system management, e.g. over IPMI works. This is untouched by the following steps and can be used during the process for recovery and setup

* Ensure network is configured for DHCP

* Instruct SUSE-IT to change VLAN for machine from 2 to 662 (example: https://infra.nue.suse.com/SelfService/Display.html?id=16458)

* Remove from osd:

```

salt-key -y -d openqaworker7.suse.de

```

* Add entry on o3 to `/etc/dnsmasq.d/openqa.conf` with MAC address, e.g.

```

dhcp-host=54:ab:3a:24:34:b8,openqaworker7

```

* Add entry to `/etc/hosts` which dnsmasq picks up to give out a DHCP lease, e.g.

```

192.168.112.12   openqaworker7.openqanet.opensuse.org openqaworker7

```

* Adapt NFS mount point

```

sed -i '/openqa\.suse\.de/d' /etc/fstab && echo 'openqa1-opensuse:/ /var/lib/openqa/share nfs4 ro,fsc 0 0' >> /etc/fstab

```

* Reload dnsmasq with `systemctl restart dnsmasq`

* Restart network on machine (over IMPI) using `systemctl restart network` and monitor in o3:`journalctl -f -u dnsmasq` until address is assigned, e.g.:

```

Feb 29 10:48:30 ariel dnsmasq[28105]: read /etc/hosts - 30 addresses

Feb 29 10:48:54 ariel dnsmasq-dhcp[28105]: DHCPREQUEST(eth1) 10.160.1.101 54:ab:3a:24:34:b8

```

* Ensure all mountpoints up

```

mount -a

```

* Change root password to o3 one

* Allow ssh password authentication: `sed -i 's/^PasswordAuthentication/#&/' /etc/ssh/sshd_config && systemctl restart sshd`

* Add personal ssh key to machine, e.g. openqaworker7:/root/.ssh/authorized_keys

* Update /etc/openqa/client.conf with the same key as used on other workers for "openqa1-opensuse"

* Update /etc/openqa/workers.ini with similar config as used on other workers, e.g. based on openqaworker4, example:

```

```

systemctl disable --now auto-update.timer salt-minion telegraf

for i in  NPI SUSE_CA telegraf-monitoring; do zypper rr $i; done

zypper -n dup --force-resolution --allow-vendor-change

```

* If the machine is not a transactional-server one has the following options: Keep as is and handle like power8 (also not transactional), enable transactional updates w/o root being r/o, change to root being r/o on-the-fly, reinstall as transactional. At least option 2 is suggested, enable transactional updates:

```

zypper -n in transactional-update

systemctl enable --now transactional-update.timer rebootmgr

```

* Enable apparmor

```

zypper -n in apparmor-utils

systemctl unmask apparmor

systemctl enable --now apparmor

```

* Switch firewall from SuSEfirewall2 to firewalld

```

zypper -n in firewalld && zypper -n rm SuSEfirewall2

systemctl enable --now firewalld

firewall-cmd --zone=trusted --add-interface=br1

firewall-cmd --set-default-zone trusted

firewall-cmd --zone=trusted --add-masquerade

```

* Copy over special openSUSE UEFI staging images, see #63382

* Check operation with a single openQA worker instance:

```

systemctl enable --now openqa-worker.target openqa-worker@1

```

* Test with an openQA job cloned from a production job, e.g. for openqaworker7

```

openqa-clone-job --within-instance https://openqa.opensuse.org/t${id} WORKER_CLASS=openqaworker7

```

* After the latest openQA job could successfully finish enable more worker instances

```

systemctl unmask openqa-worker@{2..14} && systemctl enable --now openqa-worker@{2..14}

```

* Monitor if nightly update works, e.g. look for journal entry:

```

Mar 01 00:08:26 openqaworker7 transactional-update[10933]: Calling zypper up

…

Mar 01 00:08:51 openqaworker7 transactional-update[10933]: transactional-update finished - informed rebootmgr

```

## Distribution upgrades

**Note:** Performing the upgrade differs slightly depending on the host setup:

* On hosts with a writeable `/` you need to enter a root shell i.e. `sudo bash`

* Transactional hosts require that you use `transactional-update shell` thereby creating a snapshot which is applied after a reboot, optionally using `--continue` if you want to make further changes to an existing snapshot

* Depending on available space it might be necessary to cleanup space before conducting the upgrade, e.g. use `snapper rm <N..M>` to delete older root btrfs snapshots, cleanup unneeded packages, e.g. with https://github.com/okurz/scripts/blob/master/zypper-rm-orphaned and https://github.com/okurz/scripts/blob/master/zypper-rm-unneeded

* Upgrades might pull in too many new packages so better crosscheck with `zypper … dup … --no-recommends`

* Consider using https://github.com/okurz/auto-upgrade/blob/master/auto-upgrade or manual (*Tip**: Run this in `screen -d -r || screen` and use e.g. `sudo bash`):

```

new_version=15.3 # Specify the target release

# Change the release via the special $releasever

. /etc/os-release

sed -i -e "s/${VERSION_ID}/\$releasever/g" /etc/zypp/repos.d/*

zypper --releasever=$new_version ref

test -f /etc/openqa/openqa.ini && sudo -u geekotest /opt/openqa-scripts/dump-psql

systemctl stop openqa-continuous-update.timer  # it would interfere, e.g. revert the previous zypper ref call

zypper -n --releasever=$new_version dup --auto-agree-with-licenses --replacefiles --download-in-advance

# Check config files for relevant changes

rpmconfigcheck

for i in $(cat /var/adm/rpmconfigcheck) ; do vimdiff ${i%.rpm*} $i ; done

rm $(cat /var/adm/rpmconfigcheck)

reboot

systemctl --failed

```

* Ensure that the upgrade was really successful, e.g. /etc/os-release should show the new version, the above `zypper dup` command should show no more pending actions

* Crosscheck for any obvious alerts, pipelines failing, user reports, etc.

* On any severe problems consider a complete rollback of the upgrade or also partial downgrade of packages, e.g. force-install older version of packages and zypper locks until an issue is fixed

* Monitor for successful openQA jobs on the host

## Remote management with IPMI and BMC tools

o3 and osd worker machines are controllable over IPMI from within the SUSE network, see [openqa/workerconf.sls](https://gitlab.suse.de/openqa/salt-pillars-openqa/-/blob/master/openqa/workerconf.sls) for the commands.

It is recommended to use [shell aliases](https://gitlab.suse.de/openqa/salt-pillars-openqa#get-ipmi-definition-aliases) for convenience.

`ipmitool` can sometimes behave unreliably. It seems (to okurz) as if ipmitool version ipmitool-1.8.18+git20200916.1245aaa387dc from openSUSE Tumbleweed or Factory or the "systemsmanagement" OBS repo is more reliable than the version supplied with openSUSE Leap 15.2 (See #80544#note-14) and given a stable internet connection it is certainly possible to have a consistent serial console experience.

To ensure that remotely controlled machines power on automatically after a power loss ensure to set the power restory policy to "previous", especially for new machines. Using https://gitlab.suse.de/openqa/salt-pillars-openqa/#get-ipmi-definition-aliases :

```

IFS=$'\n'; for i in $(sed 's/^alias .*="\(.*\)"/\1/' ~/.openqa_ipmi_aliases); do eval "$i" chassis policy previous; done

```

### Accessing old BMCs with "Java iKVM Viewer" when ipmitool does not work, e.g. imagetester

Imagetester can't output anything over SOL. (Likely the problem is a too old BMC version. On another system, qamaster, in 2022-10 we upgraded the BMC version (#117679#note-14) which allowed us to use ipmitool.) Therefore it is necessary to access it over the integrated iKVM console. Unfortunately java-webstart is somewhat broken and requires some extra steps to work:

1. Access the web interface of the BMC at http://imagetester-ipmi.suse.de and login via the IPMI credentials mentioned in the salt pillars repository.

2. Click on the preview image of the "Remote Console Preview" and download the according "launch.jnlp" webstart script.

3. Grab the required dependencies with curl and place them in a local directory:

```

mkdir /tmp/ikvm

curl -k https://imagetester-ipmi.suse.de:443/liblinux_x86_64__V1.0.3.jar.pack.gz > /tmp/ikvm/liblinux_x86_64__V1.0.3.jar.pack.gz

curl -k https://imagetester-ipmi.suse.de:443/iKVM__V1.69.13.0x0.jar.pack.gz > /tmp/ikvm/iKVM__V1.69.13.0x0.jar.pack.gz

```

4. Open the previous downloaded "launch.jnlp" and replace the IP in the first line from e.g. `<jnlp spec="1.0+" codebase="https://10.160.65.195:443/">` to `<jnlp spec="1.0+" codebase="http://127.0.0.1:8080/">`

5. Launch some kind of web server which can serve the previously downloaded dependencies for javaws (from /tmp/ikvm). In this example we use python: `python3 -m http.server 8080`

6. Now you can finally launch the webstart application from your modifies "launch.jnlp" file in a second console: `javaws -nosecurity -jnlp ~/Downloads/launch.jnlp`

  * It will ask you how to run the application. You can run it in a sandbox and everything still works

7. You should see the monitor output of imagetester now. "Virtual Storage" is also working which allows you to mount an ISO over this remote connection. 

*Also check https://progress.opensuse.org/issues/96719#note-27 where this was discovered. If you have questions or remarks you can ping @nicksinger*

### Accessing java based remote control clients

We also managed to start the java based remote control client from pages like

https://openqaworker4-ipmi.suse.de/ with `javaws.itweb jviewer.jnlp` from icedtea-web which offers virtual media redirection so one can select a local ISO file as installation medium.

Disclaimer: https://openwebstart.com/ explains that "Java Web Start (JWS) was deprecated in Java 9, and starting with Java 11, Oracle removed JWS from their JDK distributions". So an alternative to the outdated icedtea-web with openwebstart can be used. okurz managed the following way downloading the openwebstart .deb file from https://openwebstart.com/download/ and converted with alien:

```

wget https://github.com/karakun/OpenWebStart/releases/download/v1.6.0/OpenWebStart_linux_1_6_0.deb

sudo zypper in https://download.opensuse.org/repositories/home:/phoenix.os:/dup/15.4/noarch/alien-8.95-lp154.3.1.noarch.rpm

sudo alien --to-rpm --verbose ./OpenWebStart_linux_1_6_0.deb

sudo zypper in ./openwebstart-1.6.0-2.noarch.rpm

/opt/OpenWebStart/javaws ~/Downloads/launch.jnlp

```

In some cases we hit an error message "no iKVM64 in java.library.path" (see #117679#note-15 for details, same problem regardless of JDK version). For a local archive one can do `LD_LIBRARY_PATH=. ./iKVM`, for a webstart application there is no known solution. As workaround it is suggested to use downloaded applications from supermicro. Download "IPMIView" from https://www.supermicro.com/en/support/resources/downloadcenter/smsdownload, extract the archive, call `./IPMIView20` and connect to the desired system.

If you use your system provided JRE then you might hit the error "Certificates do not conform to algorithm constraints". Running in a terminal will tell provide more details, e.g. about SHA/RSA key lengths. Removing the line starting with `jdk.certpath.disabledAlgorithms` in /etc/crypto-policies/back-ends/java.config can fix that.

An alternative to "IPMIView" is "SMCIPMITool" from https://www.supermicro.com/en/support/resources/downloadcenter/smsdownload . This also allows to connect to systems and also use something like mounting virtual media, example:

```

$ jre/bin/java -jar ./SMCIPMITool.jar 10.162.0.4 … shell

…

10.162.0.4 X9DR3-LN4F+ (S0/G0,172w) 13:42 SIM(WA)>vmwa dev2iso /home/okurz/local/os-autoinst/os-autoinst/t/data/Core-7.2.iso

Mounting ISO file: /home/okurz/local/os-autoinst/os-autoinst/t/data/Core-7.2.iso

Device 2 :VM Plug-In OK!!

```

## openQA infrastructure needs (o3 + osd)

TL;DR: new OSD ARM workers needed, missing redundancy for o3-ppc, rest is needing replacement as nearly all current hardware is out of vendor provided maintenance (as of 2021-05), SSD storage for o3 would be good

2020-03: SUSE IT (EngInfra) provided us more space for O3 but we have only slow rotating-disk storage. Performance could be improved by providing SSD storage.

The most time and effort we currently struggle with storage space for OSD (openqa.suse.de) ~~both OSD (openqa.suse.de) as well as O3 (openqa.opensuse.org) (2020-03: Situation on o3 resolved with more storage provided by SUSE IT)~~. Both instances (OSD + O3) are using precious netapp-storage but there is currently no better approach to use different, external storage. An increase of the available space would be appreciated, ~~o3 being more important right now than osd,~~ see https://progress.opensuse.org/issues/57494 for details. Graphs like 

https://stats.openqa-monitor.qa.suse.de/d/nRDab3Jiz/openqa-jobs-test?orgId=1&from=1578343509900&to=1578653794173&fullscreen&panelId=12 show how usual test backlogs are worked on within OSD by architecture. It can be seen that both the ppc64le and aarch64 backlogs are reduced fast so we do not need more ppc64le or aarch64 machines. However, we have a stability problem with all three aarch64 workers. Potentially new machine(s) could help, see https://progress.opensuse.org/issues/41882 for details.

With number of workers and parallel processed tests as well as with the increased number of products tested on OSD and users using the system the workload on OSD constantly increases. CPU load alerts had been seen recently in #96713 and the higher load is visible in https://monitor.qa.suse.de/d/WebuiDb/webui-summary?viewPanel=25 . From time to time should increase the number of CPU cores on the OSD VM due to the higher usage.

## Setup guide for new machines

* Change IPMI/BMC passwords to use our common passwords instead of default IPMI

* OSD: Make sure to set /etc/salt/minion_id to the FQDN (see #90875#note-2 for reference)

* OSD: Add to salt using https://gitlab.suse.de/openqa/salt-states-openqa

* o3: Install with transactional-update role, then

```

echo "requires:openQA-worker" > /etc/zypp/systemCheck.d/openqa.check

sed -i 's/\(solver.dupAllowVendorChange = \)false/\1true/' /etc/zypp/zypp.conf

# configure /etc/openqa/client.conf and /etc/openqa/workers.ini, then enable the desired number of worker slots, e.g.:

```

Also copy the OVMF images for staging tests (`/usr/share/qemu/*staging*`) from other workers. Those files are from the `devel` flavor of the OVMF package built in stagings and rings, e.g. https://build.opensuse.org/package/show/openSUSE:Factory:Rings:1-MinimalX/ovmf, just renamed.

### UEFI boot via iPXE from o3 workers

Before going into iPXE-specifics, note that the MAC address of new o3 workers generally needs to be added to `/etc/dnsmasq.d/openqa.conf` and an IP address needs to be configured in `/etc/hosts` (both files are on ariel).

---

There's a PXE setup as part of `dnsmasq.service` running on ariel. It is currently configured to serve a legacy-only boot menu utilized by some tests. After following these steps, please restore this setup so tests can continue to use it.

First, make a file that contains the iPXE commands to boot available via some HTTP server. Here's how the file could look like for installing Leap 15.4 with AutoYaST:

```

#!ipxe

kernel http://download.opensuse.org/distribution/leap/15.4/repo/oss/boot/x86_64/loader/linux initrd=initrd console=tty0 console=ttyS1,115200 install=http://download.opensuse.org/distribution/leap/15.4/repo/oss/ autoyast=http://martchus.no-ip.biz/ipxe/ay-openqa-worker.xml rootpassword=…

initrd http://download.opensuse.org/distribution/leap/15.4/repo/oss/boot/x86_64/loader/initrd

boot

```

Then, setup the build of an iPXE UEFI image like explained on https://en.opensuse.org/SDB:IPXE_booting#Setup:

```

git clone https://github.com/ipxe/ipxe.git

cd ipxe

echo "#!ipxe

dhcp

chain http://martchus.no-ip.biz/ipxe/leap-15.4" > myscript.ipxe

```

As you can see, this build script contains the URL to the previously setup file. Of course commands could be built directly into the image but then you'd need to rebuild/redeploy the image all the time you want to make a change (instead of just editing a file on your HTTP server).

To conduct the build of the image, run:

```

cd src

make EMBED=../myscript.ipxe NO_WERROR=1 bin/ipxe.lkrn bin/ipxe.pxe bin-i386-efi/ipxe.efi bin-x86_64-efi/ipxe.efi

```

Note that these build options are taken from https://github.com/archlinux/svntogit-community/blob/packages/ipxe/trunk/PKGBUILD#L58 because when attempting to build on Tumbleweed I've otherwise ran into build errors.

Then you can copy the files to ariel and move them to a location somewhere under `/srv/tftpboot`:

```

# on build host

rsync bin-x86_64-efi/ipxe.efi openqa.opensuse.org:/home/martchus/ipxe.efi

# on ariel

sudo cp /home/martchus/ipxe.efi /srv/tftpboot/ipxe-own-build/ipxe.efi

```

Then configure the use of the image in `/etc/dnsmasq.d/pxeboot.conf` on ariel. Temporarily comment-out possibly disturbing lines and make sure the following lines are present:

```

enable-tftp

tftp-root=/srv/tftpboot

pxe-prompt="Press F8 for menu. foobar", 10

dhcp-match=set:efi-x86_64,option:client-arch,7

dhcp-match=set:efi-x86_64,option:client-arch,9

dhcp-match=set:efi-x86,option:client-arch,6

dhcp-match=set:bios,option:client-arch,0

dhcp-boot=tag:efi-x86_64,ipxe-own-build/ipxe.efi

```

Then run `systemctl restart dnsmasq.service` to apply and `journalctl -fu dnsmasq.service` to see what's going on.

### Installation of machines being able to run kexec

If it is possible to directly execute "kexec" on a machine, e.g. on ppc64le machines running petitboot, it is possible to start a remote network installation following https://en.opensuse.org/SDB:Network_installation#Start_the_Installation . See #119008#note-6 for an example.

### Linux Endpoint Protection Agent

Ensure any non-test OS installations have the Linux Endpoint Protection Agent deployed, see https://progress.opensuse.org/issues/123094 and https://confluence.suse.com/display/CS/Sensor+-+Linux+Endpoint+Protection+Agent for details

## Take machines out of salt-controlled production

E.g. for investigation or development or manual maintenance work

```

ssh osd "sudo salt-key -y -d $hostname"

ssh $hostname "sudo systemctl disable --now telegraf $(systemctl list-units | grep openqa-worker-auto-restart | cut -d "." -f 1 | xargs)"

```

Checkout [salt-states-openqa's examples](https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/README.md#examples) for systemd commands to start and stop workers.

## How to use samba shares to mount ISOs as virtual CD drives with SuperMicro server/mainboards

SuperMicro based servers have the capabilities to mount smb shares containing ISOs as virtual CD drives to e.g. boot from them.

Install the samba package on any machine you control. This also works from your personal workstation if the server can access it (e.g. over VPN) and create the following `/etc/samba/smb.conf`:

~~~ text

[global]

   workgroup = MYGROUP

   server string = Samba Server

   log level = 3

   client min protocol = core

   server min protocol = core

   guest ok = yes

#============================ Share Definitions ==============================

[recovery]

	comment = recovery

	path = /home/you/recovery

	public = yes

~~~

Now start the samba service. Despite the share being accessible by everyone (be carful about this!), the SuperMicro machines still need a User on the Samba server as they don't support anonymous login. To create a user without requiring a local unix user, you can use the following command:

```samba-tool domain provision --use-rfc2307 --interactive```

afterwards create a user in the samba database with:

```smbpasswd -a smbtest```

Now it should be possible to access the share. Place an ISO file into your folder configured above and use the following settings in the webui of the SuperMicro server:

"Share Host": IP of your machine running samba

"Path to Image": Path to your ISO inside the share, e.g. "\recovery\some_boot_medium.iso" (mind the backslashes!)

"Users": The username from your just created user

"Password": It's password - don't keep this empty as it will not work otherwise

After clicking on "mount" you should now see a connection to your samba server. The machine will try to mount the ISO and if everything goes well, will report "There is an iso file mounted." in the "Health Status" of the Devices.

## Bring back machines into salt-controlled production

```

ssh osd "sudo salt-key -a $hostname && sudo salt --state-output=changes $hostname state.apply"

```

Depending on your actions further manual cleanup might be necessary, e.g. `ssh $hostname "sudo systemctl unmask telegraf salt-minion"`

## Access the BMC of machines in the new security zone

One can use ssh portforwarding to access the services of a BMC (e.g. web interface) for a machine in the new security zone. The host "qe-jumpy" can be used for that like this:

~~~

ssh -4 jumpy@qe-jumpy.suse.de -L 8443:openqaworker4-ipmi.qe-ipmi-ur:443 -L 8080:openqaworker4-ipmi.qe-ipmi-ur:80

~~~

while the ssh-session is running you can then use your local browser to access the remote host by e.g. "http://localhost:8080" or "https://localhost:8443".

## Using the build-in java tools of BMCs to access machines in the security zone

*1.* Follow [Access the BMC of machines in the new security zone](#Access-the-BMC-of-machines-in-the-new-security-zone) to download the build-in java webstart file of the machine you want to control

*2.* Use nmap on qe-jumpy to scan for all ports of a machines BMC. Example:

~~~

jumpy@qe-jumpy:~> nmap openqaworker4-ipmi.qe-ipmi-ur -p-

Starting Nmap 7.70 ( https://nmap.org ) at 2023-01-17 12:23 UTC

Nmap scan report for openqaworker4-ipmi.qe-ipmi-ur (192.168.133.4)

Host is up (0.0056s latency).

Not shown: 65525 closed ports

PORT     STATE SERVICE

22/tcp   open  ssh

80/tcp   open  http

199/tcp  open  smux

427/tcp  open  svrloc

443/tcp  open  https

623/tcp  open  oob-ws-http

5120/tcp open  barracuda-bbs

5122/tcp open  unknown

5123/tcp open  unknown

7578/tcp open  unknown

~~~

*3.* Forward all ports relevant for the java applet to your local machine:

~~~

sudo ssh -i /home/nicksinger/.ssh/id_rsa.SUSE -4 jumpy@qe-jumpy.suse.de -L 443:openqaworker4-ipmi.qe-ipmi-ur:443 -L 623:openqaworker4-ipmi.qe-ipmi-ur:623 -L 5120:openqaworker4-ipmi.qe-ipmi-ur:5120 -L 5122:openqaworker4-ipmi.qe-ipmi-ur:5122 -L 5123:openqaworker4-ipmi.qe-ipmi-ur:5123 -L 7578:openqaworker4-ipmi.qe-ipmi-ur:7578

~~~

**Note 1:** You have to use the exact same ports as shown by the port scan because you cannot instruct the applet to use different ports

**Note 2:** You have to execute your ssh client with root privileges for it to be able to bind to ports below 1024. These forwardings need to be present for the applet being able to download additional files from the BMC

**Note 3:** Make sure to point to your right keyfile by using the -i parameter as ssh will scan different directories if run as root

*4.* Execute the previously downloaded applet. I use the following command to make it work with wayland:

~~~

LANG=C _JAVA_AWT_WM_NONREPARENTING=1 javaws -nosecurity -jnlp jviewer\ \(1\).jnlp

~~~

*5.* You should now be able to control the machine/BMC with all its features (e.g. mounting ISO images as virtual CD)

## Use a production host for testing backend changes locally, e.g. svirt, powerVM, IPMI bare-metal, s390x, etc.

0. Find out which type of worker slot you need for the specific job you want to run, e.g. by checking which worker slots were used for previous runs of the job on OSD or by looking for the job's worker class in the [workers table](https://openqa.suse.de/admin/workers).

1. Configure an additional worker slot in your local `workers.ini` using worker settings from the corresponding production worker. The production worker config can be found in [workerconf.sls](https://gitlab.suse.de/openqa/salt-pillars-openqa/-/blob/master/openqa/workerconf.sls) or on the hosts themselves.

2. Take out the corresponding worker slot from production using the systemd commands mentioned in [salt-states-openqa's examples](https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/README.md#examples). This is important to prevent multiple jobs from using the same svirt host.

3. Start the locally configured worker slot and clone/run some jobs.

4. When you're done, bring back the production worker slots using the systemd commands mentioned in [salt-states-openqa's examples](https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/README.md#examples).

### Alternatives

It is also possible to test svirt backend changes fully locally, at least when running tests via KVM is sufficient. Checkout [os-autoinst's documentation](https://github.com/os-autoinst/os-autoinst/blob/master/doc/backends.md#svirt=) for further details.

## Backup

Both openqa.opensuse.org and openqa.suse.de run on virtual machine clusters that provide redundancy and differential backup using snapshotting of the involved storage. SUSE-IT currently provides backups going back up to 3 days with two daily backups conducted at 23:10Z and 11:00Z. With this it is possible in cases of catastrophic data loss to recover (raise ticket over https://sd.suse.com in that case). Additionally automatic backup for the o3 webui host introduced with https://gitlab.suse.de/okurz/backup-server-salt/tree/master/rsnapshot covering so far /etc and the SQL database dumps. Fixed assets and testresults are backed up on storage.qa.suse.de (see https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/612)

### openQA database backups

Database backups of o3+osd are available on backup.qa.suse.de, acessible over ssh, same credentials as for the OSD infrastructure

### Fallback deployment on AWS

To get an instance running from a backup in case of a disaster, one can be created on AWS with this configuration:

#### Launch instance

##### Web Interface, from scratch (only if necessary, otherwise just use the template below)

- Ensure your region is **Frankfurt, Germany**

- Pick a **t3.large** with `openSUSE Leap` on AWS Marketplace

- Add two disks

    - 10 GiB for the root filesystem should be sufficient (can be easily extended later if needed)

    - The OSD database alone needs > 30 GiB and results plus assets will also need a lot (e.g. > 4 GiB for TW snapshot ISO) so take at least 100 GiB for the 2nd drive

- The security group needs to include ssh and http

- Add `openqa_created_by`, `openqa_ttl` and `team:qa-tools` tags

##### Launch from a template

Note: When you modify the template (creating a new version), be sure to set the new version as the default.

- Go to the [openQA-webUI-openSUSE-Leap](https://eu-central-1.console.aws.amazon.com/ec2/v2/home?region=eu-central-1#LaunchTemplateDetails:launchTemplateId=lt-002dfbcbd2f818e4c) Template

- Select "Actions - Launch instance from template"

- Choose your key pair

- Click "Launch instance"

###### Command line

For configuring aws cli, see [below](https://progress.opensuse.org/projects/openqav3/wiki/Wiki#Configure-aws-cli)

[aws run-instances docs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-templates.html)

    aws ec2 run-instances --launch-template LaunchTemplateId=lt-002dfbcbd2f818e4c --key-name <your-keyname>

    # or

    aws ec2 run-instances --launch-template LaunchTemplateName=openQA-webUI-openSUSE-Leap --key-name <your-keyname>

For this you have to create a key pair first, if you haven't done so.

Save the result and look for the `InstanceId`.

#### Transfer keys

Since an instance is always created with a single key, public keys of all users need to be deployed by whoever owns that key.

**Note**: `osd2` refers to the instance created above. Replace with the instance IP or add an alias to your SSH config.

    ssh openqa.suse.de "sudo su -c 'cat /home/*/.ssh/authorized_keys'" | ssh ec2-user@osd2 "cat - >> ~/.ssh/authorized_keys"

#### Bootstrapping

```

ssh osd2

sudo su

parted --script /dev/nvme1n1 mklabel gpt && parted --script /dev/nvme1n1 mkpart ext4 4096s 100%

mkfs.ext4 /dev/nvme1n1p1

vim /etc/fstab # add mount to fstab

mkdir /space && mount /dev/nvme1n1p1 /space

mkdir -p /space/pgsql/data

mkdir -p /var/lib/pgsql

ln -s /space/pgsql/data /var/lib/pgsql/data

zypper in postgresql-server # needed for user.group

chown -R postgres.postgres /space/pgsql # without correct group postgresql.service fails

mkdir -p /space/openqa

mkdir -p /var/lib/openqa

mount /space/openqa /var/lib/openqa -o bind # open also requires a lot of space 

curl -s https://raw.githubusercontent.com/os-autoinst/openQA/master/script/openqa-bootstrap | bash -x

ssh -A backup.qa.suse.de

rsync --progress /home/rsnapshot/alpha.0/openqa.suse.de/var/lib/openqa/SQL-DUMPS/2022-02-08.dump ec2-user@osd2:/tmp

ssh osd2

sudo -u postgres createdb -O geekotest openqa-osd # create pristine db for OSD import (to avoid conflicts with existing data)

sudo -u geekotest pg_restore -d openqa-osd /tmp/2022-02-08.dump # import data, will take a while (22m is a realistic time)

vim /etc/openqa/openqa.ini # change auth from Fake to OpenID

vim /etc/openqa/database.ini # change database to openqa-osd

vim /etc/openqa/client.conf # change key and secret to correct one

systemctl restart openqa-webui

```

##### Configure aws cli

You can use the command

    aws configure

but it doesn't actually help you with the possible values, so you can just create the file yourself like this:

    % cat ~/.aws/config

    [default]

    region = eu-central-1

    output = json

    % cat ~/.aws/credentials

    [default]

    aws_access_key_id = ABCDE

    aws_secret_access_key = FGHIJ

## Best practices for infrastructure work

* Same as in OSD deployment we should look for failed grafana alerts if users report something suspicious

* Collect all the information between "last good" and "first bad" and then also find the git diff in openqa/salt-states-openqa

* Apply proper "scientific method" with written down hypotheses, experiments and conclusions in tickets, follow https://progress.opensuse.org/projects/openqav3/wiki#Further-decision-steps-working-on-test-issues

* Keep salt states to describe what should *not* be there

* Try out older btrfs snapshots in systems for crosschecking and boot with disabled salt. In the kernel cmdline append `systemd.mask=salt-minion.service`

* Team should conduct a work backlog check on a daily base, e.g. look for urgent tickets related to infrastructure problems

* For hardware component replacement, create EngInfra ticket for coordination, order replacement on private expenses and get reimbursed using https://intra.suse.net/company/company-news/department/finance/claim-expenses/claim-expenses/ or have order placed with the help of line managers, let the components be delivered to the according place, e.g. SUSE Nuremberg datacenter and inform EngInfra in ticket to have them conduct the physical component replacement

* For ordering new machines follow https://mysuse.sharepoint.com/sites/SUSEBusinessCriticalLinux/Shared%20Documents/Hardware%20Order/E&I%20Hardware.pdf (get quotes from vendor, create ticket with procurement, CC osd-admins+mgriessmeier, wait for purchase order (PO) approval, order with vendor and ask them to include PO number in invoice)

* Prefer `reload` over `restart` where available e.g. `systemctl reload postgres` - in general `systemctl cat postgres` will show available commands for any service

* Test reboot stability of machines with commands like in https://progress.opensuse.org/issues/78010#note-31 e.g.

```

for run in {01..30}; do for host in $host; do echo -n "run: $run, $host: ping .. " && timeout -k 5 600 sh -c "until ping -c30 $host >/dev/null; do :; done" && echo -n "ok, ssh .. " && timeout -k 5 600 sh -c "until nc -z -w 1 $host 22; do :; done" && echo -n "ok, uptime/reboot: " && ssh $host "uptime && sudo reboot" && sleep 120 || break; done || break; done

```

# Automatic submission of packages

Every commit to the master branch of the git repositories of https://github.com/os-autoinst/os-autoinst and https://github.com/os-autoinst/openQA is considered a stable release and triggers package builds within https://build.opensuse.org/project/show/devel:openQA, in particular https://build.opensuse.org/package/show/devel:openQA/os-autoinst and https://build.opensuse.org/package/show/devel:openQA/openQA. http://jenkins.qa.suse.de/job/trigger-openQA_in_openQA-TW/ using https://github.com/os-autoinst/scripts/blob/master/trigger-openqa_in_openqa is monitoring the download repositories for new versions and triggers openQA-in-openQA tests as visible on https://openqa.opensuse.org/group_overview/24 . http://jenkins.qa.suse.de/job/monitor-openQA_in_openQA-TW/ monitors the test execution using https://github.com/os-autoinst/scripts/blob/master/monitor-openqa_job and on test success triggers http://jenkins.qa.suse.de/job/submit-openQA-TW-to-oS_Fctry/ periodically (with a build throttle as decided together with openSUSE reviewers) using https://github.com/os-autoinst/scripts/blob/master/os-autoinst-obs-auto-submit. This step prepares openQA related packages for automatic submission into openSUSE:Factory in https://build.opensuse.org/project/show/devel:openQA:tested, awaits build+check results and then creates automatic submissions to openSUSE:Factory for inclusion of packages into openSUSE Tumbleweed. This approach could also be extended for automatic submission to openSUSE Leap, SLE PackageHub or directly to SLE using maintenance updates based on a configurable schedule with additional check steps as applicable. Given that openQA are developed based on a rolling-release model with no maintenance branches any updates to base products supporting openQA would be new version updates along with dependency package updates as necessary.
