  13 == NAME
  14
  15 fsck.minix - check consistency of Minix filesystem
  16
  17 == SYNOPSIS
  18
  19 *fsck.minix* [options] _device_
  20
  21 == DESCRIPTION
  22
  23 *fsck.minix* performs a consistency check for the Linux MINIX filesystem.
  24
  25 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.
  26
  27 The _device_ name will usually have the following form:
  28
  29 ____
  30 [cols=",",]
  31 |===
  32 |/dev/hda[1-63] |IDE disk 1
  33 |/dev/hdb[1-63] |IDE disk 2
  34 |/dev/sda[1-15] |SCSI disk 1
  35 |/dev/sdb[1-15] |SCSI disk 2
  36 |===
  37 ____
  38
  39 If the filesystem was changed, i.e., repaired, then *fsck.minix* will print "FILE SYSTEM HAS BEEN CHANGED" and will *sync*(2) three times before exiting. There is _no_ need to reboot after check.
  40
  41 == WARNING
  42
  43 *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.
  44
  45 == OPTIONS
  46
  47 *-l*, *--list*::
  48 List all filenames.
  49
  50 *-r*, *--repair*::
  51 Perform interactive repairs.
  52
  53 *-a*, *--auto*::
  54 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.
  55
  56 *-v*, *--verbose*::
  57 Be verbose.
  58
  59 *-s*, *--super*::
  60 Output super-block information.
  61
  62 *-m*, *--uncleared*::
  63 Activate MINIX-like "mode not cleared" warnings.
  64
  65 *-f*, *--force*::
  66 Force a filesystem check even if the filesystem was marked as valid. Marking is done by the kernel when the filesystem is unmounted.
  67
  68 *-V*, *--version*::
  69 Display version information and exit.
  70
  71 *-h*, *--help*::
  72 Display help text and exit.
  73
  74 == DIAGNOSTICS
  75
  76 There are numerous diagnostic messages. The ones mentioned here are the most commonly seen in normal usage.
  77
  78 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".
  79
  80 == EXIT STATUS
  81
  82 The exit status returned by *fsck.minix* is the sum of the following:
  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
