[CentOS] fsck - and there was much rejoicing

Looks like the fsck bug has been stomped! I did a 960G drive this morning,
and I'm 90% of the way through a 1.4T drive, both of which have *lots* of
files and hard links, and it has *not* hung at 70.1%, and is running at
reasonable speed.

Thanks to the folks who got this one. I *really* needed to do this, esp.
to our backup drives.
