I think you may be hitting a firewall issue on port 6789, I had a similar issue recently.
The quick start preflight guide has been updated very recently for information on opening the required ports for firewalld or iptables, see link below: http://ceph.com/docs/master/start/quick-start-preflight/#open-required-ports _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
