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 SYS‐
       TEM 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  noth‐
       ing 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  com‐
       monly 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 CODES
       The exit code 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 codes 3 and 4
              8      Operational error
              16     Usage or syntax error
