IT22823: OPERATIONS THAT SEND DATA TO A DIRECTORY CONTAINER POOL FAIL WITH 'NO SPACE IS AVAILABLE' MESSAGE WHEN SPACE IS AVAILABLE.

APAR status

• Closed as program error.

Error description

• Server operations using directory container pools can fail with
  "No space is available" messages when Query Stg shows that there
   is space available.
  
  This will most likely become an issue immediately after an
  upgrade to V8
  
  For example a client backup could fail with  "ANR0522W
  Transaction failed for session 1 for node NODE1 (WinNT) - no
  space available in storage pool CONTAINER_POOL and all successor
  pools"
  
  Running the "Show sdpool CONTAINER_POOL" command shows a low (or
  zero) value for "NonDedupCntrFreeSpace"  for example:-
  
  Needs Refresh:                         False
  Maximum Size:                          0
  FsCapacity:                    154633656 MB
  FsFreeSpace:                     6782544 MB
  DedupCntrAllocSpace:           146533651 MB
  DedupCntrUsedSpace:            118378954 MB
  DedupCntrFreeSpace:             28154697 MB
  NonDedupCntrAllocSpace:           441063 MB
  NonDedupCntrUsedSpace:            439787 MB
  NonDedupCntrFreeSpace:              1276 MB
  PoolCapacity:                  153757258 MB
  PoolFree:                       34938517 MB
  Dedup Reserved Space:              96000 MB
  Non Dedup Reserved Space:              0 MB
  Compression Enabled:                   Yes
  Last Space Check:       2017-09-30 05:57:16
  
  
  In this case the NonDedupCntrFreeSpace is showing 1276 MB
  
  This APAR applies if the NonDedupCntrFreeSpace value is well
  under the totfreespace number provided via this DB2 select:
  
   Run as the instance owner:-
  
  db2 connect to tsmdb1
  db2 set schema tsmdb1
  
  db2 "select count,sum(cast(freespace as bigint)) as totfreespace
  from sd_containers sdcn where not exists (select 1 from
  sd_fragmented_containers sdfcn where sdfcn.cntrid=sdcn.cntrid)
  and type=2 and state=0 for read only with ur"
  
  
  IBM Spectrum Protect versions Affected:   Version 8.1 on all
  platforms

Local fix

• Reset the non-dedup container maxsize as follows:
  
  db2 "update sd_containers set maxsize=filesize where type=2 and
  maxsize>filesize"
  
  The run 'Q Stg' followed by 'Show SDPOOL' - which will then show
  space in  "NonDedupCntrFreeSpace"
