|jfs_fsck(8)||JFS utility - file system check||jfs_fsck(8)|
device is the special file name corresponding to the actual device to be checked (e.g. /dev/hdb1).
jfs_fsck must be run as root.
- Autocheck mode - Replay the transaction log. Do not continue fsck processing unless the aggregate state is dirty or the log replay failed. Functionally equivalent to -p. Autocheck mode is typically the default mode used when jfs_fsck is called at boot time.
- Replay the transaction log and force checking even if the file system appears clean. Repair all problems automatically.
- -j journal_device
- Specify the journal device.
- Open the file system read only. Do not replay the transaction log. Report errors, but do not repair them.
- Omit the replay of the transaction log. This option should not be used unless as a last resort (i.e. the log has been severely corrupted and replaying it causes further problems).
- Automatically repair ("preen") the file system. Replay the transaction log. Do not continue fsck processing unless the aggregate state is dirty or the log replay failed. Functionally equivalent to -a.
- Only replay the transaction log. Do not continue with a full file system check if the replay fails or if the file system is still dirty even after a journal replay. In general, this option should only be used for debugging purposes as it could leave the file system in an unmountable state. This option cannot be used with -f, -n, or --omit_journal_replay.
- Verbose messaging - print details and debug statements to stdout.
- Print version information and exit (regardless of any other chosen options).
- jfs_fsck -v -f /dev/hdb3
Check the 5th partition on the 1st hard disk, and report, but do not repair, any errors:
- jfs_fsck -n /dev/hda5
- No errors
- File system errors corrected and/or transaction log replayed successfully
- File system errors corrected, system should be rebooted if file system was mounted
- File system errors left uncorrected
- Operational error
- Usage or syntax error
- Shared library error
Please send as much pertinent information as possible, including the complete output of running jfs_fsck with the -v option on the JFS device.
