I'm trying to boot off a raid1 partition (kernel is being loaded from
a non-raid disk).  I get (on i385, NetBSD1.5R):

boot device: wd0
root on raid0a dumps on raid0b
cannot mount root, error = 6

root@orava ~ # disklabel -r wd4
# /dev/rwd4d:
type: RAID
disk: ibm45g
...

root@orava ~ # disklabel -r wd5
# /dev/rwd5d:
type: RAID
disk: ibm45g
...

root@orava ~ # disklabel -r raid0
# /dev/rraid0d:
type: RAID
disk: raid45g
...

root@orava ~ # raidctl -s raid0
Components:
           /dev/wd4e: optimal
           /dev/wd5e: optimal
...
   RAID Level: 1
   Autoconfig: Yes
   Root partition: Yes
   Last configured as: raid0
...

What did I do wrong? :)

Thanks,
