Re: PG down & incomplete

Another thing... since your osd.10 is near full, your cluster may be
fairly close to capacity for the purposes of rebalancing.  Have a look
at:

http://ceph.com/docs/master/rados/configuration/mon-config-ref/#storage-capacity
http://ceph.com/docs/master/rados/troubleshooting/troubleshooting-osd/#no-free-drive-space

Maybe we can get some others to look at this.  It's not clear to me
why the other OSD crashes after you take osd.25 out. It could be
capacity, but that shouldn't make it crash. Have you tried adding more
OSDs to increase capacity?
