Input/output error is the generic "I couldn't talk to the server" error message from Ceph mounts, there are multiple reasons for it. Perhaps there is something useful in the kernel logs, see /var/log/kern.log. You may have for example configured the server to demand authentication, and the above mount line is without authentication. What you see with ceph -w is the clusters internal heartbeat etc traffic. Also, note that we don't recommend using the kernel client on the same machine that is serving the Ceph cluster -- there are known deadlocks there, under memory pressure, unrelated to Ceph (NFS would trigger the same problem). Cfuse should be safe. -- :(){ :|:&};:
