Error description

• Replication of large size objects might fail by the reason of
  insufficient free space in the target directory storage pool or
  cloud storage pools using cloud cache even though there is
  enough space in the target container to ingest objects.
  
  When replicating node data, IBM Storage Protect server allocates
  the replication reserved space on the target directory container
  or cloud cache container before receiving objects. Usually it
  preallocates the same size as the total size of objects.
  However, for a large size object that is greater than 10 GB, the
  server falsely allocates the larger size of reserved space than
  the object size. As a result, replication might fail by the
  reason of insufficient target storage space in spite of the fact
  that there is enough free space.
  
  The value of "Replication Reserved Space" can be seen in output
  SHOW SDPOOL while the replication process is running.
  
  
  IBM Storage Protect Versions Affected:
  IBM Storage Protect Server 8.1 on supported platforms
  
  
  Additional Keywords:
  ANR4369I, ANR0522W, ANR0206E, TS015706582
  

Local fix

• It might be mitigated by specifying greater value than 1 to
  PreallocReductionRate option on the target server when data
  deduplication or compression percentage is high.
