After looking at the dmesg output, I am curious whether you are using
the promise sataII 150 TX4 controller for the raid disks?  I see you are
using 6.0-RELEASE whereas I'm using 5.4-STABLE with that particular
controller.  My dmesg output for the disk array looks like the
following:

ad4: 238475MB <HDT722525DLA380/V44OA80A> [484521/16/63] at ata2-master
SATA150
ad6: 238475MB <HDS722525VLSA80/V36OA60A> [484521/16/63] at ata3-master
SATA150
ad8: 238475MB <HDT722525DLA380/V44OA80A> [484521/16/63] at ata4-master
SATA150
ad10: 238475MB <HDT722525DLA380/V44OA80A> [484521/16/63] at ata5-master
SATA150
ar0: 953900MB <ATA RAID0 array> [65535/255/63] status: READY subdisks:
 disk0 READY on ad4 at ata2-master
 disk1 READY on ad6 at ata3-master
 disk2 READY on ad8 at ata4-master
 disk3 READY on ad10 at ata5-master

The device I mount as my raid filesystem is ar0s1 and I believe it
corresponds to ``device ataraid'' in the kernel.  I read the raid
mirroring page in the handbook, although, I'm thinking your controller
should represent each disk as ``ar0'' and handle the mirroring itself
(possibly consisting of two sets of two disks).  I really don't know
though.

It looks like the RAID1 mirroring tutorial is for systems that don't
actually have a raid controller.  Hence, the RAID0 tutorial is the one
that I would be using if I did not use the promise controller.  Because
I _DO_ use the controller, I am simply able to manipulate the ar0 disk
array as a single disk.  I imagine your setup will differ, but I hope
this helps.
