Bug Description

There are 2 issues here:

  1. When the source directory/FS is created for a PV and is immediately consumed, then an incorrect quota is set on the target directory based on the consumed source size instead of the assigned quota of the source.
  2. This triggered a QuotaScan requirement on the target PowerScale cluster. Further target PV creations on the same RG will fail due to the SyncIQ job failure if the triggered QuotaScan is not completed by that cluster on time.

The fix involves

  1. Setting right quota on the target directory OR ELSE no new writes can be performed on the target side post failover.
  2. Have a workaround/retry logic if the SyncIQ job fails due to QuotaScan requirement.
  3. Documentation updates

Logs

None.
