Should > /etc/ceph/ceph.conf be copied over to the client ? Yes, you can do that. If you haven't got ceph.conf on the client, you'll need to give the "-m" parameter to rbd in order to specify the IP-address of a monitor node to connect to. If you use cephx authentication, the client will also need a file containing the secret or a keyring. -- Jens Kristian Søgaard, Mermaid Consulting ApS, jens@xxxxxxxxxxxxxxxxxxxx, http://www.mermaidconsulting.com/ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
