Some of the files that were encountered during the move operation were skipped because they contained pending fragments.
Large files that are stored in deduplication-enabled storage pools are split into smaller pieces or fragments for performance reasons. When fragments are copied or moved to another storage pool, they are marked pending until all fragments that comprise the file arrive at the target storage pool. The pending state is removed from the fragments once all fragments have been successfully moved.
The operation skips the files without making copies and continues.
Server processes such as BACKUP STGPOOL, MOVE DATA, MOVE NODEDATA and storage pool migration can result in fragments being marked as pending. You can issue the QUERY PROCESS command to see whether any of the processes are running. If so, retry the operation at a later time when the fragments are not pending.
