Actually, I'm using ceph as the system datastore. I used the cephfs (CEPH FUSE) and mounted it on all nodes on /var/lib/one/datastores/0/
Regarding ssh for trasfer driver, I haven't really used it since I'm all on ceph, both system and image datastore. I may be wrong but that is how I understand it from the docs. --- Thanks, Kenneth Apollo Global Corp.
