Perhaps it also depends how they handle the raid of a whole disk.
Are you trying to boot from that raid?
Forgot to ask what is in your /etc/mdadm/mdadm.conf and the IDs of the disks
IMO the problem is that if it is not a partition the mdadm can not assemble
as it is looking for a partition, but not sure how grub or whatever handle
it when you boot off the drive.
The drives use normal /dev/sd* ids. They are not being booted from. I
had updated /etc/mdadm/mdadm/conf with the new information for the array
after creating it.
When I did exactly the same thing after creating a single FD00 partition
on the drives, everything worked.
