snapdiff.rebl.absent.allocated.block

Severity: INFORMATIONAL
Description: This message occurs when SnapDiff®, the snapshot copy differencing engine, encounters an absent allocated block. The absent allocated block is replicated to destination as raid error and Replication is unaffected by this issue.
Corrective Action: None. Zombie count of 0 is expected even when zombie processing is ongoing.
Syslog Message: Encountered an absent allocated block on inode %u in snapshot copy ID %u of volume %u Zombie processing: %u.
Parameters: inode_num (INT): Identifier of the affected file.
snap_id (INT): Identifier of the Snapshot copy.
fsid (INT): Identifier of the volume.
zombie_processing (INT): Ongoing zombie processing.

Severity: NOTICE
Description: This message occurs when SnapDiff®, the snapshot copy differencing engine, encounters an invalid access time for an inode. Future accesses of the inode should not only succeed, but also reset its access time to a valid value. Replication is also unaffected by this issue.
Corrective Action: Run the (privilege: advanced) "inodepath -v volume_name inode_number" command to find the path of the affected file from the inode number, and modify the file within the Active File System. Note that file attributes captured in a snapshot copy cannot be changed.
Syslog Message: Encountered invalid access time on inode %u in Snapshot copy ID %u of volume %u.
Parameters: inode_num (INT): Identifier of the affected file.
snap_id (INT): Identifier of the Snapshot copy.
fsid (INT): Identifier of the volume.
