IJ33419: MANUAL RESYNC COMMAND SHOULD RECLAIM DELETED INODES FOR REUSE

APAR status

• Closed as program error.

Error description

• mmafmctl command has a provision to reclaim deleted
  inodes when Resync is manually run.
  This causes the inodes to be reclaimed only under
   some conditions and not reclaimed in other cases.
  

Local fix

• 1. A full resync and then recovery needs to be run in order to
      reclaim deleted inodes.
  
  2. A resync with afmSkipResyncRecovery at the cluster level
      tuned using the mmchconfig command should be run..
     Fileset level tuned doesn't work today.
  
  3. Worst case an mmfsck needs to be run to reclaim the inodes.
  

Problem summary

• mmafmctl command has a provision to reclaim deleted
   inodes when Resync is manually run.
  This causes the inodes to be reclaimed only under
   some conditions and not reclaimed in other cases.

  Benefits of the solution:
  Manual Resync run through the mmamctl command will
   be able to reclaim those
   deleted inodes which are awaiting replication
   to the remote site.
  
  Work around:
  1. A full resync and then recovery needs to be run in order to
      reclaim deleted inodes.
  
  2. A resync with afmSkipResyncRecovery at the cluster level
      tuned using the mmchconfig command should be run..
     Fileset level tuned doesn't work today.
  
  3. Worst case an mmfsck needs to be run to reclaim the inodes.
  
  Problem trigger:
  Running manual resync on fileset without recovery, with
   afmSkipResyncRecovery flag set on the fileset level.
