  12 == NAME
  13
  14 fsck.minix - check consistency of Minix filesystem
  15
  16 == SYNOPSIS
  17
  18 *fsck.minix* [_options_] _device_
  19
  20 == DESCRIPTION
  21
  22 *fsck.minix* performs a consistency check for the Linux MINIX filesystem.
  23
  24 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.
  25
  26 The _device_ name will usually have the following form:
  27
  28 ____
  29 [cols=",",]
  30 |===
  31 |/dev/hda[1-63] |IDE disk 1
  32 |/dev/hdb[1-63] |IDE disk 2
  33 |/dev/sda[1-15] |SCSI disk 1
  34 |/dev/sdb[1-15] |SCSI disk 2
  35 |===
  36 ____
  37
  38 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.
  39
  40 == WARNING
  41
  42 *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.
  43
  44 == OPTIONS
  45
  46 *-l*, *--list*::
  47   List all filenames.
  48
  49 *-r*, *--repair*::
  50   Perform interactive repairs.
  51
  52 *-a*, *--auto*::
  53   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.
  54
  55 *-v*, *--verbose*::
  56   Be verbose.
  57
  58 *-s*, *--super*::
  59   Output super-block information.
  60
  61 *-m*, *--uncleared*::
  62   Activate MINIX-like "mode not cleared" warnings.
  63
  64 *-f*, *--force*::
  65   Force a filesystem check even if the filesystem was marked as valid. Marking is done by the kernel when the filesystem is unmounted.
  66
  67 *-V*, *--version*::
  68   Display version information and exit.
  69
  70 *-h*, *--help*::
  71   Display help text and exit.
  72
  73 == DIAGNOSTICS
  74
  75 There are numerous diagnostic messages. The ones mentioned here are the most commonly seen in normal usage.
  76
  77 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".
  78
  79 == EXIT STATUS
  80
  81 The exit status returned by *fsck.minix* is the sum of the following:
  82
  83 ____
  84 *0*::
  85   No errors
  86 *3*::
  87   Filesystem errors corrected, system should be rebooted if filesystem was mounted
  88 *4*::
  89   Filesystem errors left uncorrected
  90 *7*::
  91   Combination of exit statuses 3 and 4
  92 *8*::
  93   Operational error
  94 *16*::
  95   Usage or syntax error
