I am running NetBSD-1.5.1_BETA2.

I am building a Raid10 set which consists of 4 ide disks, wd0, wd1, wd2 &
wd3. Wd0 & Wd2 are in a pair and wd 1 & wd3 are in a pairs.

First I build raid1 set as follows:
wd0 & wd2
a:     500M         0   4.2BSD  1024 8192 16
c:  30000M        0   unused
d:  30000M        0   unused
e:       500M 500M  RAID      # swap disk   - raid0
f:    20000M 1000M RAID     # /  - raid1
g:   27000M  30000M RAID   # strip - raid2

wd1 & wd3

c: 15000M   0   unused
d: 15000M   0   unused
e:  15000M   0  RAID              # strip -raid3

The configuration of raid1 for raid0, raid1, raid2, raid3 is ok. Then I am
stuck as to how to configure the disklabel of raid2 & raid3 for stripping.
I have man page, it is very brief on the makeup of raid.conf for raid on
raid. However my problem is that I cannot setup the disklabel of raid2 and
raid3 by assigning e partition for raid as this:

raid2
d:  27000M   0   unused
e:  27000M   0    RAID
raid3
d:  15000M   0   unused
e:  15000M   0    RAID
When I replace the disklabel by doing disklabel -R -r raid2
/root/disklabel.raid2, I got the error message saying:

disklabel: warning: unused partition e: size 27000M offset 0

Anyone has experienced setting up raid10 set?
