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

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
       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         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.

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

       -h, --help
              Display help text 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
       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
