OK, I'm still trying to solve this.  Though the server has been up rock
steady, but the errors concern me.  I built this on a test box months ago
and now that I am thinking, I may have built it originally on a drive of a
different manufacturer, although about the same size (20g).  This may have
something to do with it.  What is the easiest way to get these errors
taken care of?  I've tried e2fsck, and also ran fsck on Vol00.  Looks like
I made a fine mess of things.  Is there I wasy to fix it without reloading
Centos?  Here are some outputs:

Warning: start=63 - this looks like a partition rather than
the entire disk. Using fdisk on it is probably meaningless.
[Use the --force option if you really want this]
