The FAQ/howto is badly out of date. It would be interesting to see the event counter on the failed device. With mdadm you can reassemble the array and start it even though the event counters disagree. I had to do this recently when a failed drive caused a partial boot, and my array (on attempting to boot) was incrementing the first of the drives' event counters. I knew nothing had changed, so it was very safe to force. This might be a similar situation. I'd guess the worst thing you would face is a few corrupted files. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
