Ok, the second sites procedure worked like a charm, and things are now being moved out of the RAID to get things back up. I'm pondering using this chance to upgrade the RAID size, since it was running low on space. Though most of it is due to me being lazy and not cleaning out some of the data hiding on the server that I really have no use for.

And mark, thanks for the suggestion. I'll probably do a dd ignoring errors on the pure /dev/hd[x] devices though to be able to sense errors on the exact drives, instead of catting the md device.
