IJ26438: ASSERT EXP(CONTEXT != UNKNOWNOP) IN MOVEDATABETWEENPOOLS

APAR status

• Closed as program error.

Error description

• For pre-4.1 file systems, after the mmquotaoff command
  deactivates
  user/group/fileset quota, the old quota file will be
  deinstalled and converted to a normal file. If the system pool
  cannot contain the data, the old quota file will need to be
  moved
  from the system pool to a data pool. If the file system has
  DMAPI
  enabled (-z yes), the deinstallation process will encounter
  assert exp(context != unknownOp) in moveDataBetweenPools
  

Local fix

• Use mmchfs -z no  to disable DMAPI first before
  running mmquotaoff command
  

Problem summary

• For pre-4.1 file systems, after the
  mmquotaoff command deactivates
  user/group/fileset quota, the old quota file will be
  deinstalled and converted to a
  normal file. If the system pool
  cannot contain the data, the old
  quota file will need to be moved
  from the system pool to a data
  pool. If the file system has DMAPI
  enabled (-z yes), the deinstallation
  process will encounter
  assert exp(context != unknownOp) in
  moveDataBetweenPools
  

Problem conclusion

• Benefits of the solution:
  Avoid the assert
  
  Work Around:
  Use mmchfs -z no  to disable DMAPI first before
  running mmquotaoff command
  
  Problem trigger
  mmquotaoff, a pre-4.1 file system, DMAPI enabled
