Hi, The story: - raid5 set with four disks - after power outage two disks were marked faulty - reassembled the set with 3 disks (1,2,3) - added the forth disk - reconstruction of the set failed because of an uncorrectable sector of disk 3 - tried to reassemble the set with disk 1,2,4. Not possible because disk 4 is in spare mode. Any opportunities to get the set back with disks 1,2,4? Thanks in advance for your help. mdadm v1.9.0 linux 2.6.12.3 Cheers Meik - 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
