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... Cheers, John.
