fsck.minix - check consistency of Minix filesystem
fsck.minix [options] device
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.
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.
-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 extensive 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.
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 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
