Description
Motivation¶
- Need to upgrade machines before EOL of Leap 15.4 and have a consistent environment
Acceptance criteria¶
- AC1: all LSG QE salt controlled machines run a clean upgraded openSUSE Leap 15.5 (no failed systemd services, no left over .rpm-new files, etc.) except for OSD workers
Acceptance tests¶
- AT1-1:
sudo salt -C 'not G@roles:worker and not G@roles:webui' grains.get oscodename | grep -B1 'Leap 15.4'is empty
Suggestions¶
- read https://progress.opensuse.org/projects/openqav3/wiki#Distribution-upgrades
- Reserve some time when the related services are not heavily relied upon
- Keep IPMI interface ready and test that Serial-over-LAN works for potential recovery or for virtual machines virt-manager access
- After upgrade reboot and check everything working as expected, if not rollback, e.g. with
snapper rollback
Rollback actions¶
- Remove silence
alertname=Failed systemd services
Further details¶
- Don't worry, everything can be repaired :) If by any chance the machines gets misconfigured in many cases there are btrfs snapshots to recover, the IPMI Serial-over-LAN, etc.
