You need to see which filesystem is whining.  Then you probably need to
fsck that filesystem.  This can take two forms:

	fsck -y /dev/hdax

(replace "x" with the partition of the offending filesystem) or

	fsck -y /fsname

(replace "/fsname" with the label of the filesystem).

The odds are that it's pooping out on /usr or /var (/usr/share/man is
where the man pages live), so "fsck -y /usr" should recover /usr
(if you used filesystem labels).  If you didn't use labels, check the
/etc/fstab file to see the device names of the partitions and use the
first form I mentioned above.  Be warned that you _may_ lose or truncate
some files during the fsck process (especially ones that were being
written to when the crash occurred).
