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 possi-
       bility 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 dele-
       tion.
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  exten-
              sive 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 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
