- NAME
- fsck, fsck1 - perform file system consistency check
- SYNOPSIS
- fsck [-aclmrs] [device] ...
- OPTIONS
- -a Automatically repair inconsistencies
- -c Check and list only the specified i-nodes
- -l List the files and directories in the filesytem
- -r Prompt user for repairs if inconsistencies are found
- -s List the superblock of the file system
- EXAMPLES
- fsck /dev/hd4 # Check file system on /dev/hd4
- fsck -a /dev/at0 # Automatically fix errors on /dev/at0

- fsck -c 2 3 /dev/hd3

- DESCRIPTION
- Fsck performs consistency checks on the file systems which reside on the
- specified devices. Fsck1 is an alternate version for use on obsolete V1
- file systems. When either the -a or -r flags are given, the file system
- will be repaired if errors are found. Before running fsck on a mounted
- file system, it must first be unmounted. Trying to repair a mounted file
- system is dangerous and should not be attempted.
- To repair the root file system (which cannot be unmounted), first type
- CTRL-F9 at the console to kill any and all processes. Log back in as
- root, type sync to force any buffered changes to disk, run fsck on the
- root file system and immediately reboot the computer by typing reboot.
- It is necessary to kill all processes before repairing the root file
- system to prevent them from modifying any disk blocks while fsck is
- running. This is only necessary for the root file system, any other file
- system can simply be unmounted before it is checked.
