Your hardware raid threw a IO error. This should _not_ happen.
You probably have a almost broken disk. Hardware error which results in
xfs shutting the filesystem down.
Should I upgrade to a new kernel and XFS release before investigating this
further? System info and some kernel log excerpts are below; the full
kernel log (events related to this) can be downloaded from

XFS is not at fault here, although a newer kernel might alleviate or at
least provide more info about the hardware problem.
I am curious as to what raid controller you use.
Some raid controllers from adaptec have a tendency to get their panties
in a knot and die under heavy IO (updatedb).
