closed[alert] Host powerqaworker-qam-1.qa.suse.de is down size:M
0%
Description
Leads to the OSD deploment piplining failing so the host has been removed from salt.
Rollback steps¶
- Add the worker back to salt
Updated by mkittler about 2 years ago
I restarted the pipeline and it passed again (after removing the host from salt). So the pipeline failure was really just due to that.

Similar to other power workers on that Leap version the journal just ends and a power reset helps to recover the machine:

Updated by okurz about 2 years ago
Same as we have on qa-power8-3 as well. The important action is to use the old kernel. Please also apply the same consistent change on all our power workers in production. Anyway, it's helpful information to learn that other ppc64le hosts are affected by the same product issue the same. Could you please comment accordingly on the bugilla issue?

This worker crashes with a much lower frequency than the other hosts. Maybe it is the same issue, maybe just the same symptom. Since we didn't really pin down the source of the problem so far it is really hard to tell. This host doesn't crash very often (first time I need to recover it in fact) so I thought it would be better to keep it on the version we use everywhere else (downgrades should still be the exception) and to see how the situation develops. Of course we can still downgrade the machine if it becomes too unstable.
Updated by mkittler about 2 years ago
It has crashed again. I've already recovered the machine but this means the worker can now officially be considered unstable like the others. Well, to be sure I'd like to keep it at least for a few days on Leap 15.4. If it stay unstable than https://bugzilla.opensuse.org/show_bug.cgi?id=1202138 is the related product bug.
Note that there's again nothing interesting in the journal (which just ends which no prior error messages or sign of an attempted shutdown).

Updated by okurz about 2 years ago
Based on the feedback in the bug report we can't expect more help for bare-metal based OPAL installations it seems. So I suggest to rollback the kernel version to according to #119008#note-14 .
So I did
zypper in --oldpackage http://download.opensuse.org/update/leap/15.3/sle/ppc64le/kernel-default-5.3.18-150300.59.93.1.ppc64le.rpm http://download.opensuse.org/update/leap/15.3/sle/ppc64le/util-linux-2.36.2-150300.4.23.1.ppc64le.rpm && zypper rm kernel-default-5.14.21-150400.24.28 kernel-default-5.14.21-150400.24.21 && for i in kernel-default util-linux; do zypper al --comment "poo#119008, kernel regression boo#1202138" $i; done && reboot

Ok, good. Note that qa-power8-4-kvm.qa.suse.de (the first host where we encountered the problem) was just set back to a previous snapshot by me at the time. So it is running under Leap 15.3. I'll boot a Leap 15.4 snapshot and perform the same downgrade there so all workers are on Leap 15.4 at least.
Updated by mkittler about 2 years ago
That's actually not easily possible anymore. The worker was too long on 15.3 so all 15.4 snapshots have already been cleaned up (cat /.snapshots/*/snapshot/etc/os-release | grep 15.4 shows nothing). Not sure whether it makes sense to upgrade it to Leap 15.4 anymore at this point (just to downgrade the kernel anyways). (All of this is out of the scope of this ticket anyways.)
Updated by livdywan about 2 years ago
FYI the machine is currently up and running. Assuming the upgrade was not stable, in this context we can probably leave it as is and consider it working (upgrades are not part of this ticket).
Updated by mkittler about 2 years ago
- Status changed from Feedback to Resolved
And powerqaworker-qam-1 itself seems to be stable under the downgraded kernel so I suppose this issue can be closed. (The host up alert for the worker has already been resumed as well.)
