Inconsistency types

Reported inconsistencies in the FSE check log may be the following:

•missing in FSC

A file is reported as missing in FSC when its file ID exists in Fast Recovery Information, but not in FSC. To resolve the problem, do one of the following:

•Run the File System Catalog recovery. For details, see File System Catalog recovery, page 235.

•Run consistency check of the File System Catalog and enable automatic correction. For details, see Consistency check of FSC vs. FSE media, page 182.

•missing on media

A file is reported as missing on media, when the migration process did not succeed. The related file information has been recorded in FSC, but failed to be stored to Fast Recovery Information or FSE media.

To resolve the problem, do one of the following:

•Manually migrate the file using the command fsefile --trigger-migration.

•Wait for next restart of the FSE implementation. The file will be migrated automatically.

•no NSC

•mismatch report, such as:

•Wrong file size

•Wrong file name

•Wrong owner-ID

•ADS name

•Not last NSC
