FSCK.MINIX(8)                System Administration               FSCK.MINIX(8)

NAME
       fsck.minix - check consistency of Minix filesystem

SYNOPSIS
       fsck.minix [options] device

DESCRIPTION
       fsck.minix performs a consistency check for the Linux MINIX filesystem.

       The program assumes the filesystem is quiescent. fsck.minix should not
       be used on a mounted device unless you can be sure nobody is writing to
       it. Remember that the kernel can write to device when it searches for
       files.

       The device name will usually have the following form:

          +---------------+-------------+
          |               |             |
          |/dev/hda[1-63] | IDE disk 1  |
          +---------------+-------------+
          |               |             |
          |/dev/hdb[1-63] | IDE disk 2  |
          +---------------+-------------+
          |               |             |
          |/dev/sda[1-15] | SCSI disk 1 |
          +---------------+-------------+
          |               |             |
          |/dev/sdb[1-15] | SCSI disk 2 |
          +---------------+-------------+

       If the filesystem was changed, i.e., repaired, then fsck.minix
       will print "FILE SYSTEM HAS CHANGED" and will sync(2) three times
       before exiting. There is no need to reboot after check.

WARNING
       fsck.minix should not be used on a mounted filesystem. Using
       fsck.minix on a mounted filesystem is very dangerous, due to the
       possibility that deleted files are still in use, and can
       seriously damage a perfectly good filesystem! If you absolutely
       have to run fsck.minix on a mounted filesystem, such as the root
       filesystem, make sure nothing is writing to the disk, and that no
       files are "zombies" waiting for deletion.

OPTIONS
       -l, --list
           List all filenames.

       -r, --repair
           Perform interactive repairs.

       -a, --auto
           Perform automatic repairs. This option implies --repair and
           serves to answer all of the questions asked with the default.
           Note that this can be extremely dangerous in the case of
           extensive filesystem damage.

       -v, --verbose
           Be verbose.

       -s, --super
           Output super-block information.

       -m, --uncleared
           Activate MINIX-like "mode not cleared" warnings.

       -f, --force
           Force a filesystem check even if the filesystem was marked as
           valid. Marking is done by the kernel when the filesystem is
           unmounted.

       -V, --version
           Display version information and exit.

       -h, --help
           Display help text and exit.

DIAGNOSTICS
       There are numerous diagnostic messages. The ones mentioned here
       are the most commonly seen in normal usage.

       If the device does not exist, fsck.minix will print "unable to
       read super block". If the device exists, but is not a MINIX
       filesystem, fsck.minix will print "bad magic number in
       super-block".

EXIT STATUS
       The exit status returned by fsck.minix is the sum of the
       following:

       0
           No errors

       3
           Filesystem errors corrected, system should be rebooted if
           filesystem was mounted

       4
           Filesystem errors left uncorrected

       7
           Combination of exit statuses 3 and 4

       8
           Operational error

       16
           Usage or syntax error
