Hi all, one of my servers has experienced degradation in one of its RAID arrays:
root@micro ~ # cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sda3[0] 1424121720 blocks super 1.2 [2/1] [U_] md1 : active raid1 sda2[0] sdb2[1] 29295544 blocks super 1.2 [2/2] [UU] md0 : active (auto-read-only) raid1 sda1[0] sdb1[1] 11716536 blocks super 1.2 [2/2] [UU] unused devices: <none> Following some online tutorials for RAID array recovery Iam trying to re-insert /dev/sdb3 into /dev/md2: root@micro ~ # mdadm --add /dev/md2 /dev/sdb3 mdadm: add new device failed for /dev/sdb3 as 2: Invalid argument As you can see it fails to re-insert the component! Whats suspicious is that /dev/sdb1 and /dev/sdb2 are just fine in other 2 RAID components, so I don't think that the /dev/sdb drive has failed! Any suggestions are welcome!
