So I can successfully map within the container, but when I try to `mkfs.ext4 -m0 /dev/rbd0` I get:
Oct 09 19:31:03 deis-2 sh[1569]: mke2fs 1.42.9 (4-Feb-2014)
Oct 09 19:31:03 deis-2 sh[1569]: mkfs.ext4: Operation not permitted while trying to determine filesystem size
Once the device is mapped within the container, though, I can successfully format the volume on the host.

Adding `-v /dev:/dev` works as expected - after mapping, the device shows up as /dev/rbd0. Agreed, though - I thought --privileged should do this.Chris Armstrong

This could be a docker bug - my understanding is that all devices have
to show up if running with --privileged, which I do on my test box.
I'll poke around some more as well.
Thanks,
