Description
Motivation¶
Seems like o3 machines do not automatically reboot anymore, likely because we continuously call zypper dup
so that the nightly upgrades don't find any changes?
See #111758#note-18
Acceptance criteria¶
- AC1: O3 machines are rebooted after updates requiring a reboot
- AC2: Eventually root filesystem snapshots are cleaned up
Suggestions¶
- Monitor machines for some weeks to keep track of updates
- Check that there's no pending kernel update, can be done with
for i in openqaworker1 openqaworker4 openqaworker7 imagetester rebel power8; do ssh root@$i "zypper ps | tail -n 2"; done
- Revisit the update logic to only upgrade openQA packages instead of everything. We discussed this and came to the conclusion that we created an ugly Frankenstein-Monster which nobody should do. Yet another confirmation that the proper way(s) to go are either a fully rolling distribution, aka. Tumbleweed, or transactional-update server + container with continuously deployed workload on top

so "nothing to update" and nothing is done, no reboot is triggered.

so some machines are up since 37 days and not rebooted. We discussed in weekly SUSE QE Tools unblock 2022-07-06 and agreed that likely the best approach is to just use the openqa-auto-update service which also, same as the transactional update, will most likely never need to install anything as the continuous update already does but it will check if a reboot is needed and request a reboot over rebootmgr. And with the maintenance window still setup correctly to be nightly there will be a nightly reboot but only when necessary.
I did
for i in openqaworker1 openqaworker4 openqaworker7 imagetester rebel power8; do ssh root@$i "systemctl enable --now openqa-auto-update.timer"; done
and now back to monitoring over the next days.
EDIT: Wait, where is aarch64? … Ah, it's missing! Apparently we had openQA-auto-update installed on all machines but not on aarch64. Fixed that with zypper -n in openQA-auto-update && systemctl enable --now openqa-auto-update.timer

As we were missing tooling on power8 I did zypper -n in lsof rebootmgr && systemctl enable --now rebootmgr
.
And then check again all with:
for i in aarch64 openqaworker1 openqaworker4 openqaworker7 imagetester rebel power8; do echo "## $i" && ssh root@$i "zypper ps | tail -n 2; rebootmgrctl status; uptime"; done
and all looks fine.
