It sounds like the Ceph services are being stopped before it gets to the unmounts. It probably can't unmount the rbd cleanly so shutdowm hangs.
Btw mounting with the kernel client on an OSD node isn't recommend.

MarcusThanks!,Does anyone have any idea how I might fix this?I've traced it back to systemd; it shuts down part(s?) of ceph before unmounting or unmapping the block devices, so when it tries to do so it hangs.For a home server project I've set up a single-node ceph system.Everything works just fine; I can mount block devices and store stuff on them, however the system will not shut down without hanging.
If this weren't systemd I'm sure I could find a place to kludge it, but I've had no such luck.
