Description

Observation

This was problematic in the past, see #173947. I had a brief look on s390zl12.oqa.prg2.suse.org but couldn't find much I could easily remove.

The caused an alert when the disk usage was for two hours at 88 %, see https://monitor.qa.suse.de/d/GDs390zl12/dashboard-for-s390zl12?orgId=1&viewPanel=panel-65090&from=2025-02-13T08:30:31.456Z&to=2025-02-13T09:30:26.604Z&timezone=browser&var-datasource=000000001&refresh=1m. Since disk usage is now back at 82 % it isn't clear what caused this.

Acceptance Criteria

  • AC1: The disk usage is considerably below the 80% alert threshold

Suggestions

  • Use a bigger disk which is possible because we have a virtual device but 40GB should actually be enough for a special purpose OS instance
  • Limit space used by snapshots … if snapshots actually are the culprit
  • As this is about the root filesystem and we have a separate one for /var/lib/libvirt/images it should be certainly feasible to reach well below 40GB with the root f/s. Just use btrfs fi du / $something or variants to find out where we loose the space and cleanup
  • Re-run commands from #173947#note-8 again and try to make sense of the output.
