Hi all,
I am running Kubernetes on CoreOS and use rbd binary exctracted from
ceph/ceph-docker/config image to map images to CoreOS host. Everything works
just fine except when trying to unmap the volume. It doesn't unmap and gives
following error:
$ rbd showmapped
id pool imagesnap device
Also I can confirm that doing echo > /sys/bus/rbd/remove does unmap
the device, though not rbd unmap
