What is the difference between ceph rbd and iscsi in the context of Cinder volume (of type ceph)?

Question

I am trying to get a volume driver to work on a docker swarm which uses nova instances and cinder volume and makes persistent storage available for the swarm services. I can only create cinder volumes of type ceph. I am modifying the driver and trying to get it to work for me, but I cannot get the TargetPortal, TargetIQN etc to do the iscsi attach. Should I be using RBD instead of iscsi since the volume type is ceph?

Answer 1

I got this working using the Rexray. iscsi is not supported for cinder in my case. That is why these details are not returned by openstack endpoint during attach for the cinder-docker-driver.
