	If you have a RAID controller, why do you want to use LVM for
striping?  But the question is still valid, and one I'd be very
interested in the answer to.  I'm interested in the reverse case.  :-)

	I've been using reiserfs for quite awhile, and while I'm not
someone who gives an fs a lot of abuse, it has functioned perfectly for
me.  It's also faster than ext2 in most cases, despite the journaling,
and it wastes a lot less space.

Have fun (if at all possible),
The best we can hope for concerning the people at large is that they
be properly armed.  -- Alexander Hamilton
