IT39164: MAINTENANCE JOB WARNING "SNAPSHOT(S) WITH ACTIVE CLONE(S) COULD NOT BE DELETED" FOR VSNAP CLONE VOLUMES FROM ARCHIVE BACKUPS

APAR status

• Closed as program error.

Error description

• Clone volumes on the vSnap with names prefixed with
  "vsnap_arc_upload_" are used during archive jobs and are
  expected to be cleaned up upon archive completion.
  This type of volume still can be present after a crash of the
  vSnap host while an archive operation was running.
  The maintenance job in IBM Spectrum Protect Plus cannot expire
  archive snapshots due to these left over clone volumes.
  In the maintenance job log the following messages will be seen
  each day with a growing list of snapshots that cannot be
  expired :
  INFO,..,CTGGA1914,Delete Cloud Snapshot <xxxx> on partner
                    archive partner id <vSnapArchivePartnerId>
                    on vSnap.
  INFO,..,CTGGA1911,Cloud Snapshot delete session started for
                    snapshot <xxxx> partner type archive
                    partnerId <vSnapArchivePartnerId> cloud
                    session null on cloud <yyyy>
  WARN,..,The following snapshot(s) with active clone(s) could
          not be deleted.

  IBM Spectrum Protect Plus Versions Affected:
  IBM Spectrum Protect Plus 10.1.x
  
  Additional Keywords: SPP, SPPLUS, TS007044930
  

Local fix

• Manually clean up the left over clone volumes :
  1. Ensure no archive jobs are currently active.
     As long as no archive jobs are running, any volumes named
     "vsnap_arc_upload_" should not exist.
  2. Use this command to list and delete them:
        vsnap volume show | grep vsnap_arc_upload_ | awk '{print
  $1}' | while read cloneId; do echo "Deleting clone volume id
  $cloneId"; vsnap volume delete --id $cloneId --force --noprompt;
  done

Problem conclusion

• The problem occurred because temporary clone volumes created by
  the archive upload process could be left behind in some cases if
  the vSnap server crashed abruptly. The leftover clones prevent
  expiration of the underlying snapshots, thus causing warnings or
  errors in the Maintenance job. The problem has been resolved by
  implementing code fixes to detect and clean up leftover archive
  clones during vSnap startup.
