Oh, and if your cluster is busy enough that there's always some
rebalancing going on, you might never get to 100% active+clean. In
that case, I do believe that "ceph pg dump" probably contains all the
information needed, and --format=json makes it parseable, but it's
just not currently documented. We really should provide a good way of
accessing that information.

I filed http://tracker.newdream.net/issues/2394 to keep track of this task.
