Error description
Moving data out of a deduplicated storage pool with either MOVE DATA or MOVE NODEDATA commands can cause data integrity issues if the RECONSTRUCT parameter is set to NO. Any data that had been linked in the deduplicated storage pool at the time of the move operation will be corrupted in the target pool. The following ANR9999D message is one symptom of this issue: ANR9999D_XXXXXXXX BfGetBitfileExtents(bfaggrut.c:4298) Thread<598>: BFBE Entry not found for object BITFILE_ID (SESSION: SESSID) ANR9999D_XXXXXXXX bfRtrv(bfrtrv.c:982) Thread<598>: Total size of extents (EXTENT_ID) doesn't match original size (SIZE) for object (BITFILE_ID2) in super bitfile (SUPERBITFILE_ID) (SESSION: SESSID) ANR0546W Retrieve or restore failed for session SESSID for node NODENAME - internal server error detected. (SESSION: SESSID) Another symptom of this problem is that occupancy numbers for the node(s) that were moved will be invalid which will be evident from Q OCCupancy output or messages issued to the activity log. The symptoms may vary depending upon the operation that attempts to access these files and the extent of the corruption. The overall theme is that there will be some missing parts to the bitfile which in most cases will be a missing extent.
