      AFS service/operation meeting

      hardware failure
      how to avoid involving the cloud team
      Arne's input, warm standby + VLDB update
      Jose's input and the new cloud resources

      cold recovery tests, updated statement

      RQF2630026 perf qual metric
      RQF2626035, ticket routing

      Fons absence

      Decisions:

      • Investigate the "warm standby" scenario which involves reattaching rbd volumes and updating VLDB
      • Follow up on how we could do the VM "evacuation" if necessary (Arne proposed a rundeck job)
      • Old harware
        • Plan a move, after understanding if "warm standby" increases our options
          • if not, normail drain workflow
      • Cold recovery tests
        • Write and exercise a procedure to create a new AFS cell and restore a single volume there
          • Need to find relevant backups on CTA
          • Our restore machinery presently assumes the CERN.CH cell
      • Follow up on the Service Perf Qualification stuff
