/home mounts a RAID1 mirrored array, /dev/md0, made up of two identical 1TB Western Digital disks, bought about 6 to 9 months ago.
mdadm has kicked one of these disks out of the array twice in the last 24 hours.
[T]onight it's happened again, and the same command results in
#mdadm --manage /dev/md0 --add /dev/sdd1 mdadm: Cannot open /dev/sdd1: Device or resource busy
Does this mean that sdd is failing and needs to be replaced? I sort of know the answer I'm going to get, but thought I'd check here first, in case I was missing something obvious.
Could be cable, controller, disk, or even some rare kernel bug, but it is probably the disk. If you can get the RAID1 sync'd and healthy again, you might try, shutting down, swapping the cables, and seeing if the problem follows the disk or the cable. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
