Unfortunately i have no the box nor the original disks, only the raw copy of the drives. I know this is hard, but this is a challenge for me. I know that, the original raid structure was RAID5 from 3 disks + 1 spare. The owner tried to move the disks across the slots, now i have found only one original superblock, but this looks like strange too for me: /dev/sdi3: Magic : a92b4efc Version : 00.90.00 UUID : 9604e5ec:2c1ee6c4:39d34560:27adacf1 Creation Time : Tue Jan 24 15:13:05 2006 Raid Level : raid5 Device Size : 195069184 (186.03 GiB 199.75 GB) Array Size : 390138368 (372.06 GiB 399.50 GB) Raid Devices : 3 Total Devices : 3 Preferred Minor : 0 Update Time : Mon May 10 12:43:09 2010 State : clean Active Devices : 1 Working Devices : 2 Failed Devices : 1 Spare Devices : 1 Checksum : 682ebe56 - correct Events : 0.116 Layout : left-asymmetric Chunk Size : 4K Number Major Minor RaidDevice State this 3 33 3 3 spare 0 0 56 3 0 active sync 1 1 57 3 1 faulty 2 2 0 0 2 faulty removed 3 3 33 3 3 spare My questions: - If this is a spare drive, should be moved (rebuild) to the #2 no, because the #2 failed and than removed, no? - how can be "clean" this array? - Is there a way to get information about the failing order or time? (The May 10 was the fail of the nas.) Somebody have any idea, how can this be? Thanks, Janos Haar
