hi all, I am trying to get ceph work with openstack havana. I am following the instructions here. https://ceph.com/docs/master/rbd/rbd-openstack/
However, I found i probably need more details on openstack. The instruction mentioned cinder-volume nodes. How about cinder-api cinder-scheduler? Do I also need one extra node for these two modules? Also, it mentioned that ceph does not need cinder? Then why does it illustrate the installation with cinder volume? To my understanding, ceph will try balancing the storage in th cluster. Then what does cinder-scheduler do here? Same job? Which one rules? Thanks Geeks!
