The easiest broad check is just to look at iowait. ;) If this does turn out to be the problem we can get into the details of addressing it, but honestly this is something we're still discussing (we can throttle easily based on bandwidth but are still determining how best to throttle random IO). Also of course, these are warnings that operations are taking a while, but if your "user" is still happy then the system will keep running. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com > And hm, I'll look at the networking.
