I believe this is wrong. You need to create a partition on each disk
and offset it from the beginning of the disk by at least one cylinder.
All three partitions on your three disks should be of the same size
(which is not a problem, since your disks are the same). Partitions
can be either of sandard ffs type or, as recommended in the man page,
of type RAID (if your platform supports it. i386 does)

And this should be:
/dev/wd0j
/dev/wd0j
/dev/wd0j

('j' is name of the partition that you created as I said above. You
can use any letter for the partition name. I usually use 'p' for raid
partitions)

'man raid' and 'man raidctl' are great references to setup a raid.

Hope this helps.
