The solution for HA cinder is the parameter <host> in /etc/cinder/cinder.conf on the machines that are running cinder-volume service.
If you set this parameter to the same string on all the hosts that are running cinder-volume service than all the hosts will be parent to any volume in the ceph cluster, so any host can create a volume from an already existing volume.
So I am suggesting to close the bug as designed. I will log a bug against the documentation.
