NAME
fsck.minix - a file system consistency checker for Linux
SYNOPSIS
fsck.minix [ -larvsmf ]
device
DESCRIPTION
fsck.minix
performs a consistency check for the Linux MINIX filesystem. The current
version supports the 14 character and 30 character filename options.
The program
assumes the file system 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 files).
The device 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 file system 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.
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 (i.e., the root filesystem), make sure nothing is
writing to the disk, and that no files are "zombies" waiting for deletion.
OPTIONS
-l
Lists all filenames
-r
Performs interactive repairs
-a
Performs 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 file system
damage.
-v
Verbose
-s
Outputs super-block information
-m
Activates MINIX-like "mode not cleared" warnings
-f
Force file system check even if the file system was marked as valid (this
marking is done by the kernel when the file system is unmounted).
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 file system,
fsck.minix
will print "bad magic number in super-block".
EXIT CODES
The exit code returned by
fsck.minix
is the sum of the following:
0
No errors
3
File system errors corrected, system should be rebooted if file system was
mounted
4
File system 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.
