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.
