Hello Stackers,

It seems we're hitting a bug within the Cinder Volume service. The problem presents itself when creating a Ceph RBD backed Volume using an originating snapshot.

Yes, this reflects a non-current version, to be precise Cinder 17.4.

However, does this look familiar to someone, maybe?

Thanks!
