Note that whatever the best course of action is I think the wiki should probably be updated with clear instructions on that. I'm willing to document this myself and probably other Gotchas (like how to fix a 4-device RAID10 filesystem when one of them fails based on the recent discussion I've seen here) but I'm not sure I know all the details and wouldn't want to put incomplete information in the wiki so I'll wait for answers before starting to work on this. The data on this filesystem isn't critical and I have backups for the most important files so I can live with a "degraded" state for a while until I'm sure of the best way to proceed.
