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 ex-
       iting.  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 un-
	      mounted.

       -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 su-
       per  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
