root@fw1dv:~# cat /proc/mdstat
Personalities : [raid1] 
unused devices: <none>

There shouldn't be any other array of any sort running. Our config should 
account for the entirety of the drives. I wonder if there is something wrong 
with the config that I'm trying to use? That it used to work doesn't 
necessarily mean that perhaps an adjustment is not in order, does it?
