I have just had a similar incident and recovered similarly. So now I am wondering about recovery in the event of a real failure. Could this be accomplished by configuring a softraid with only 1 disk? e.g.
bioctl -c 1 -C force -l /dev/sd2a softraid0 given that sd3a suffered the failure? Is there any documentation about recovery of failures in a softraid partition?
