Hello! I have cluster of 3 machines with ceph 0.80.10 (package shipped with Ubuntu Trusty). Ceph sucessfully mounts on all of them. On external machine I'm reciving error "can't read superblock" and dmesg shows records like: [1485389.625036] libceph: mon0 [...]:6789 socket closed (con state CONNECTING) >From external machine i can sucessfully telnet to ports listened by mon and mds daemons and see banner like ceph v027z �*�� - �*� � External machine's network is listed in ceph public networks. External machine running Ubuntu Lucid with kernel 3.8.0. When trying to mount there aren't any related records in master mds log or any monitors log. Machines are connected by ipv6.
