Does it? It sounds more like an administrative action than a current 
status. I would have thought "online" or "offline" - unless that means 
something else somewhere else.

And for mdadm state: how about "busy" and "idle"? Hmm maybe just "busy" 
instead of "active" or "dirty"; we don't want to start an array with 
--assume-idle...
