Try (not sure if it will help): # nbd-client -d /dev/nbd0 This is part of the "nbd" package (or whatever is the name in your distribution), not of ceph. -- Alexander E. Patrakov CV: http://pc.cd/PLz7

You can restart the "rbd-nbd" daemon by running "rbd-nbd map --device /dev/nbd0 <image-spec>"

You can restart the "rbd-nbd" daemon by running "rbd-nbd map --device /dev/nbd0 <image-spec>"
works, but when I try to unmap, the command block the terminal and never end (I cannot even kill it). Same with nbd-client. Detail: only happens with journaling enabled. -- Herbert

Luminous is EOL -- any chance you can reproduce using an Octopus "rbd-nbd" client?
