       fsck.minix - check consistency of Minix filesystem

       fsck.minix [-larvsmf] device

       fsck.minix performs a consistency check for the Linux MINIX filesystem.
       The current version supports the 14 character and 30 character filename

       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  (and	 remember that the kernel can write to it when it searches for

       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.	 Since Linux does not currently have raw devices, there is  no
       need to reboot at this time.

       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 (i.e., the root filesystem), make sure nothing is
       writing to the disk, and that no files are "zombies" waiting for	 dele‐

       -l     List all filenames.

       -r     Perform interactive repairs.

       -a     Perform  automatic  repairs.  (This option implies -r 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     Be verbose.

       -s     Output super-block information.

       -m     Activate MINIX-like "mode not cleared" warnings.

       -f     Force a filesystem check even if the filesystem  was  marked  as
	      valid (this marking is done by the kernel when the filesystem is

       fsck(8),	   fsck.ext(8),	   fsck.ext2(8),    fsck.xiafs(8),    mkfs(8),
       mkfs.minix(8), mkfs.ext(8), mkfs.ext2(8), mkfs.xiafs(8), reboot(8)

       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".

       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

       8      Operational error

       16     Usage or syntax error

       In point of fact, only 0, 3, 4, 7, 8, and 16 can ever be returned.
