If I want to remove an osd, I use 'ceph out' before taking it down, i.e. stopping the OSD process, and removing the disk. How do I (preferably programatically) tell when it is safe to stop the OSD process? The documentation says 'ceph -w', which is not especially helpful, (a) if I want to do it programatically, or (b) if there are other problems in the cluster so ceph was not reporting HEALTH_OK to start with. Is there a better way?
We've had some discussions about this recently, but there's no great way of doing this right now. We should probably have a query option that returns "number of PGs on this OSD" or some such.
