Comment 4 for bug 1809210

For clarity, the commands used to remove the services (via ssh on one of the Cinder units):

For each service that isn't relevant any longer:
cinder-manage service remove cinder-volume <service-name>

In this case, the unwanted services:
cinder@LVM
juju-958f87-5-lxd-11@CEPH
juju-958f87-22-lxd-17@CEPH
juju-958f87-13-lxd-9@CEPH
juju-958f87-13-lxd-11@CEPH
