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.
Best regards,
