- .SH DESCRIPTION
- .PP
- fIFsckfR performs consistency checks on the file systems which reside
- on the specified devices.
- fIFsck1fR is an alternate version for use on obsolete V1 file systems.
- When either the fB-afR or fB-rfR flags are given, the file system
- will be repaired if errors are found.
- Before running fIfsckfR on a mounted file system, it must first be unmounted.
- Trying to repair a mounted file system is dangerous and should not be
- attempted.
- .PP
- 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 fBrootfR, type fIsyncfR to force any buffered changes to disk,
- run fIfsckfR on the root file system and immediately reboot the
- computer by typing fIrebootfR.
- .PP
- It is necessary to kill all processes before repairing the root file system
- to prevent them from modifying any disk blocks while fIfsckfR is running.
- This is only necessary for the root file system, any other file system can
- simply be unmounted before it is checked.
