IJ53480: ASSERTION ENCOUNTERED DURING MMRECLAIMSPACE

APAR status

• Closed as program error.

Error description

• Assertion `*errP != E_OK || amP == NULL || amP->getPoolId() ==
  poolId' in mmreclaimspaceDue to a coding error, instead of using
  poolIndex, poolId was used to access an internal array of disks
  in the storage pool, causing assertion. The assertion is hit
  when the file system has thin disks with more than one storage
  pools.
  

Local fix

Problem summary

  Benefits of the solution:
  Remove error code.
  
  Work Around:
  None
  
  Problem trigger:
  During mmreclaimspace, reclaimReservedThinSpaceInPool() invoked
  accessAllocMapById wrongly using 'poolIndex' instead of 'poolId'
  leading to the assertion.The assertion is hit when the file
  system has thin disks with more than one storage pools.
  
  Symptom:
  Daemon fails with an assertion
