== 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:
|
|
|
|
____
|
|
[cols=",",]
|
|
|===
|
|
|/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 BEEN CHANGED" and will *sync*(2) three times before exiting. 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 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.
|
|
|
|
== 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 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.
|
|
|
|
== 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 super 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
