Read up on loopback devices. Sorry, never done it, can't help
personally, but it sticks a ram-disk layer between mdadm and the actual
disk.
So the disks themselves are read-only, and you can try things out to see
what works. If it fails, you throw the loopback layer away, if it works
you can run it on the disk itself.
Cheers,
Wol
