So I ran Memtest and checked for other hardware issues. Then I ran the XFS_Reapir, I wound up having to run it with the -L switch to clear the logs as the disks were unmountable. This appears to have worked. Chatting with The Wiz, we came to the conclusion that the system got too hot as this occured during a parity check. The door was closed to the room it is in and it just got too hot and the controller probably went offline briefly. This in turn offlined several disks at once and the resulting havoc ensued.
Thanks for the assistance.
