Oh, you're right — I just ran a grep and didn't look closely enough. It looks like once they're in that too_full state, they need to get kicked by the OSD to try again though. I believe (haven't checked) that that can happen if other backfills finish, but if none are running and all the PGs needing backfill are in this state, a restart isn't terribly lightweight but will provide the kick needed. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com
