What Happens When Diagnosis Appears to Fail?
Errors occurring on ZYQ files cause FSCK to issue a warning and continue. In these
cases, the new catalog might still contain minor inconsistencies.
Any other errors occurring during writes to the new catalog files cause FSCK to issue
an error message and terminate.
When FSCK restarts a failed run that has renamed ZYQ files, it restores these files and
attempts to update the PXINODE file accordingly. If an I/O error occurs during this
update, FSCK issues a warning and attempts to continue.
The FSCK run might fail if there is a file input or output error. If you place fileset
catalogs on mirrored volumes, you eliminate most I/O errors on catalog files.
If FSCK encounters:
•
Any read error on the old catalog other than Guardian File Management Error 1
(reaching an end of file), it issues an error message and terminates abnormally.
•
A Guardian File Management Error 1 (reaching an end of file) on the new PXLINK
file, FSCK issues a warning message and continues.
Any other errors occurring during writes to the new catalog files cause FSCK to
issue an error message and terminate.
•
Any error other than Guardian File Management Error 1 (reaching an end of file)
on FSCK’s inode swap file, FSCK issues an error message and terminates.
•
An inconsistency in its internal data structures, it issues an error message and
terminates.
If the FSCK run fails, the fileset that FSCK is checking enters the UNKNOWN state
rather than the STOPPED state. If this happens, check the FSCK log file (described
under FSCK Log File on page 5-24). If FSCK failed before writing anything to this file,
the file is probably full. Either rename the file or copy it to another volume, then purge
the original file.
Deleting a Fileset
If your site uses the OSSREMOV utility, that utility deletes all filesets. See
OSSREMOV Utility on page C-17 for more information.
To delete a single fileset:
1. Determine whether the fileset is mounted by using the SCF STATUS FILESET
Command.
