"non-fresh" is because of that "events" counter in superblock of sda1 is at least 2 lesser that others. >Dec 23 12:30:19 alfred kernel: raid5: device sdc1 operational as raid disk 3 >Dec 23 12:30:19 alfred kernel: raid5: device sdb1 operational as raid disk 0 >Dec 23 12:30:19 alfred kernel: raid5: cannot start dirty degraded array for md0 here "dirty" results from system crash while writing data to the raid. using "--froce" param with mdadm could start the raid, or md-mod has a param "start_dirty_degraded", if you load it with "start_dirty_degraded" set to 1, your raid5 could be started. I think no more data would lose or corrupt if only doing raid start operation, but you should first get more replies and suggestion :) -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
