action #157996

Updated by okurz about 1 month ago

## Motivation 

 * Need to upgrade machines before EOL of Leap 15.5 15.4 and have a consistent environment 

 ## Acceptance criteria 
 * **AC1:** all LSG QE salt controlled machines run a clean upgraded openSUSE Leap 15.6 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 15.5'` 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.
