Observation

# systemctl --failed
systemctl: /lib64/libselinux.so.1: no version information available (required by /usr/lib/systemd/libsystemd-shared-249.so)

* var-lib-openqa-share.mount   loaded failed failed /var/lib/openqa/share
* transactional-update.service loaded failed failed Update the system

so service fails and weird error messages when executing commands but openQA tests seem to be running so far.

Acceptance criteria

  • AC1: No failed services on openqaworker1
  • AC2: openqaworker1 reboots cleanly multiple times

Suggestions

  • Over IPMI check why machine does not boot, as necessary with a physical display and keyboard
  • Check filesystem, potentially need to replace hardware
  • Check failed services

Out of scope

  • Trying to recover the usual IPMI connection, see #117625

I physically connected a VGA monitor, a USB keyboard and my personal USB recovery thumbdrive with grml.org. Booted into the grml live system (UEFI mode, BIOS mode left me at grub rescue, possibly broken) and from there on could assemble raids and chroot into the system and conduct a proper system upgrade in the hope that this also fixes problems with the kernel or the initrd:

mdadm --assemble /dev/md1
mkdir -p /mnt/md1
mount /dev/md1 /mnt/md1
for i in sys proc dev dev/pts run ; do mount /$i /mnt/$i; done
chroot /mnt/md1 /bin/bash

and within there zypper said something about Leap 15.3 but /etc/os-release said 15.4 so I did

zypper --releasever=15.4 ref && zypper --releasever=15.4 dup

and after that another zypper dup call for consistency. I also did zypper in --force kernel-default and saw the kernel and initramfs configured

Also found an error message about a + in /usr/lib/plymouth/plymouth-populate-initrd. I fixed that but likely a non-critical warning because locally I also have that. dheidler also mentioned that he saw that recently.

To check the installation I called

qemu-system-x86 -enable-kvm -nographic -snapshot -hda /dev/sdb -hdb /dev/sdc

and could observe the system showing the grub menu fine and also loading the inital ramdisk but didn't progress from there within 1 minute so I aborted and tried again the full system boot. The system booted fine now and a second try as well. After boot I could see that var-lib-openqa-share.mount is listed as failed. But if I start the mount unit that works fine so the problem seems to be due to not waiting properly for the network being fully up.

In the journal I can find:

so the automount triggers the mounting which can not yet be done in this state of the system and then containers fail. I do not know how to continue.

There are different problems:

  1. We can not rely on the systemd target network-online. Custom scripting is necessary to wait until network is available
  2. Do not rely on NFS mounts on openQA workers, use the cache service instead or just clone stuff from git which you need

Marius in Slack:

About the s390x containers:

  1. For the problem of knowing what dependencies to install one could actually rsync the directory but with a filter to only look for install_deps.. Or we create a specific container for the opensuse test distribution on OBS that has the required dependencies already installed. Likely that would be the cleanest solution as it would also avoid running zypper manually at all.
  2. For the problem of providing tests/needles we should enable the cache service for those workers. For this to work we need to map port 9530 into the container and to map the cache directory (by default /var/lib/openqa/cache/) into the container.

So the idea is the following:

We created a new container that is based on the existing openqa worker container but is distri-opensuse specific and installs the dependencies rpm on startup (not on container build time as the test distribution might change and we don't want to update the container base image in this case).

The new containers with that new base image will now use the cache service. The cache service on the host was configured to be reachable from containers and the cache dir is mounted into the containers. The worker code within the container needs a PR that will allow to point it to a cache service that is not listening at 127.0.0.1.

All the above can only be actually used after the PRs are accepted and an updated container image is available. Until then we manually fixed the current setup with nfs which will work until the next reboot, so that openqa can process some jobs in the meantime.

In a related discussion https://suse.slack.com/archives/C02CANHLANP/p1666359531628739 fvogt provided related issue reports https://github.com/openSUSE/wicked/pull/836 and https://bugzilla.suse.com/show_bug.cgi?id=1172684 and https://jira.suse.com/browse/PM-1982 confirming the hypothesis that wicked's treating of the systemd targets network.target and in particular network-online.target is unexpected, unreliable and not time-optimal.

I see two ways to go forward:

I prefer the latter

The containers are now coming up on boot and use the cache service of the host.

For the network stack replacement it wouldn't be trivial as there are very many tap devices to be configured.
Maybe that large number of devices to bring up could be the reason why the network comes up that slow in the first place.
When watching the bootup via IPMI console, I could see that the network only comes up about half a minute after there is already a login prompt on the tty.

Anyway that would be a topic for a different ticket.
