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:

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

-r, --repair

-a, --auto

-v, --verbose

-s, --super

-m, --uncleared

-f, --force

-h, --help

-V, --version

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

3

4

7

8

16
