Hi,
I installed opensuse 10.3b2 on my server having 4 identical hard drives.
on each drive is an 290 gb partition used for raid5. It seems, that the
setup program created a degenerated array of sd[abc]2 and added the last
as a spare drive. mdadm -D /dev/md1 reports:
/dev/md1:
Version : 01.00.03
Creation Time : Sun Aug 26 14:23:29 2007

2 8 34 2 active sync /dev/sdc2
4 8 50 3 spare rebuilding /dev/sdd2
and /proc/mdstat shows:
Personalities : [raid6] [raid5] [raid4] [raid0] [raid1] [linear]
md0 : active raid1 sda1[0] sdd1[3] sdc1[2] sdb1[1]
72248 blocks super 1.0 [4/4] [UUUU]
bitmap: 0/9 pages [0KB], 4KB chunk
md1 : active raid5 sda2[0] sdd2[4] sdc2[2] sdb2[1]
937488384 blocks super 1.0 level 5, 128k chunk, algorithm 2 [4/3]
[UUU_]
bitmap: 6/299 pages [24KB], 512KB chunk
unused devices: <none>
There is no hard disk activity, so I guess md1 is not rebuildinh even if
mdadm states so.
Is there a way to include the spare disk into the array?
Why is this not done automaticaly?
Greetings
Marc
