NAME         top

       fsck.minix - check consistency of Minix filesystem

SYNOPSIS         top

       fsck.minix [options] device

DESCRIPTION         top

       fsck.minix performs a consistency check for the Linux MINIX

       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 BEEN CHANGED" and
       will sync(2) three times before exiting. There is no need
       to reboot after check.

WARNING         top

       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         top

       -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.

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

       -V, --version
           Print version and exit.

DIAGNOSTICS         top

       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         top

       The exit status returned by fsck.minix is the sum of the

           No errors

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

           Filesystem errors left uncorrected

           Combination of exit statuses 3 and 4

           Operational error

           Usage or syntax error
