[opensuse] mdadm keeps breaking my array

Hi,

I'm running openSUSE 11.1 with KDE 3.5.10.

/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. The first time this happened, I issued

#mdadm --manage /dev/md0 --add /dev/sdd1
mdadm: re-added /dev/sdd1

so it appeared to be happy to put this disk back into the array.

However, tonight 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.

Bob
