Description

Motivation

  • Need to upgrade workers before EOL of Leap 15.3 and have a consistent environment

Acceptance criteria

  • AC1: all o3 worker machines run a clean upgraded openSUSE Leap 15.4 (no failed systemd services, no left over .rpm-new files, etc.)

Suggestions

  • read https://progress.opensuse.org/projects/openqav3/wiki#Distribution-upgrades
  • Reserve some time when the workers are only executing a few or no openQA test jobs
  • Keep IPMI interface ready and test that Serial-over-LAN works for potential recovery
  • Use the instructions from above but use transactional-update shell for transactional update workers
  • After upgrade reboot and check everything working as expected, if not rollback, e.g. with transactional-update rollback

Further details

  • Don't worry, everything can be repaired :) If by any chance the worker gets misconfigured there are btrfs snapshots to recover, the IPMI Serial-over-LAN, a reinstall is possible and not hard, there is no important data on the host (it's only an openQA worker) and there are also other machines that can jobs while one host might be down for a little bit longer. And okurz can hold your hand :)
