Guess that was me. A simple "chassis power cycle" did the trick.

Interesting. But do you know what caused the problem then?

but also ssh service failed

I've rejected the salt-key for now on OSD to prevent automatic startup of workers. What I found while booting is that the systems hangs for quite some time with the last message being printed: [ 1034.526144] kexec_file: kernel signature verification failed (-129). - which seems to fit with @okurz suggestion that this is caused by kernel updates.

[…] seems to fit with @okurz suggestion that this is caused by kernel updates.

but what I meant is only that some package upgrades, for example kernel updates, trigger a reboot which is all according to plan. Have you seen #78010#note-9 regarding the systemd services? I suspect that this is simply again or still a problem of systemd service dependencies and fully in our control.

please see #77011#note-18 for changes that fvogt has applied. We should crosscheck the changes he did, commit to salt and ensure this is applicable for all machines and then apply the same to all, o3 and osd.

So I diffed with what fvogt did:

I'm not convinced yet that this will resolve our problem. I'd rather like to look into why our array-devices are busy in the first place.
I suspect that something assembles our array before we format and therefore assume we have a dependency problem.

From a first, quick look I think it could be related to mdmonitor.service. From https://linux.die.net/man/8/mdadm:

[…] all arrays listed in the configuration file will be monitored. Further, if --scan is given, then any other md devices that appear in /proc/mdstat will also be monitored. 

Which would explain why the device is busy. I will experiment with some dependencies for our service to run before mdmonitor

well, seems like this custom image was (blindly? Or was I pressing Enter where no console showed up?) reinstalling the worker. At least this is how it looks to me:

• Observed a "host up alert" today, ssh would time out, hit ^D via ipmi
• ssh claims it's not the expected host anymore and my key is denied... apparently I hit another corner case, which I worked around by explicitly specifying the key... 🙄
• systemctl list-units --failed w/ no obvious way to fix i.e. restarting the service won't work

On 2021-02-22, openqaworker3 failed to reboots (was: [Alerting] openqaworker3: host up alert). just like https://progress.opensuse.org/issues/78010#note-20 said.

openqa_nvme_format.service failed on openqaworker3 after it rebooted success. (was: [Alerting] Failed systemd services alert (except openqa.suse.de)),
Checking in: https://stats.openqa-monitor.qa.suse.de/d/KToPYLEWz/failed-systemd-services?orgId=1

The result in openqaworker3 is:

xiaojing@openqaworker3:~> sudo systemctl --failed
  UNIT                       LOAD   ACTIVE SUB    DESCRIPTION

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

openqaworker3 not ready today, blocking osd-deployment. Manually continued boot process with ^D

Mentioned MR: https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/474

Looks like it succeeded 10 reboots. I've just started another round of reboots.

openqaworker8 is fully online again. Unpaused the corresponding host-up alert in grafana. Next candidate for testing could be again openqaworker3 as for this ticket. On openqaworker3 did systemctl mask --now telegraf salt-minion openqa-worker-cacheservice && systemctl mask --now openqa-worker-auto-restart@{1..13}

checked stability in a loop with

for run in {01..30}; do for host in openqaworker3; 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

and all 30 reboots were successful.

In the journal we can check if the retry was triggered:
