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
