142 Monitoring and maintaining FSE
• not in NSC
A file is recorded as missing in NSC because the FSE implementation has been upgraded to release
2.1 in the past, but recovery of FSC has not been performed yet. In such case, you need to run
fserecover --fsc PartitionName to update NSC. For details, see section ”File System Catalog
recovery” on page 186.
The following mismatches can also be a result of upgrading to release 2.1 without performing FSC
recovery afterwards.
• suspicious
A file is recorded as suspicious when it is created on the HSM file system but does not have a file ID. It
is possible that the FSE implementation is unaware of its existence. This can happen in situations, such
as:
• The disk was full when the file was created and the FSE attributes could not be written.
• The file was created before the platform-native file system was mounted as an HSM file system (for
example, the lost+found directory).
• A power failure occurred and the file ID was not written or the Hierarchical Storage Manager did
not get the event request.
• offline file is prolonged or not shortened
Files that have not been released properly or which have not been fully recalled due to an error have
the Prolonged status. In such cases, the file is in an offline state but still occupies storage space. To
resolve the problem, first recall the file by accessing it, and then release it with the
fsefile --release command.
• mismatch report, such as:
•MigrationID mismatch
•Owner mismatch
• Name mismatch
• Not all attributes in NSC
•Size mismatch
