Apologies for a somewhat off-topic question, but...
The Linux kernel doesn't properly detect my software RAID1+0 when I boot up. It detects the two RAID1 arrays, the
partitionsof which are marked properly. But it can't find the RAID0 on top of that, because there's no corresponding
deviceto auto-detect. The result is that it creates /dev/md0 and /dev/md1 and assembles the RAID1 devices on bootup,
but/dev/md2 isn't created, so the RAID0 can't be assembled at boot time.
Here's what it looks like:
$ cat /proc/mdstat
Personalities : [raid0] [raid1]
md2 : active raid0 md0[0] md1[1]
234436224 blocks 64k chunks
md1 : active raid1 sde1[1] sdc1[2]
117218176 blocks [2/2] [UU]
md0 : active raid1 sdd1[1] sdb1[0]
117218176 blocks [2/2] [UU]
$ uname -r
2.6.12-1.1381_FC3
After a reboot, I always have to do this:
mknod /dev/md2 b 9 2
mdadm --assemble /dev/md2 /dev/md0 /dev/md1
mount /dev/md2
What am I missing here?
Thanks,
Craig
