Yeah, and extra 0 jumped in there. Faulty keyboard I guess. :) OS
and everything but base is on the RAID-1.

Well, there's a lot of people who use xfs and ext3. XFS is generally
rated higher than ext3 both for performance and reliability. However,
we run Centos 5 in production, and XFS isn't one of the blessed file
systems it comes with, so we're running ext3. It's worked quite well
for us.
