As example, after creating and then stopping md8 I restarted it with only 
one of the members. Mdadm told me how to force it...

[root@wombat looptesting]# mdadm --assemble /dev/md8 /dev/loop1
mdadm: /dev/md8 assembled from 1 drive - need all 2 to start it (use --
run to insist).

[root@wombat looptesting]# mdadm --assemble /dev/md8 /dev/loop1 --run
mdadm: /dev/md8 has been started with 1 drive (out of 2).
