Ceph

After having a mismatch for the client.admin.keyring in a new host that I needed to get a monitor running I was getting the following output:

vagrant@node3:~$ ls /var/lib/ceph/mon/ceph-node3/
vagrant@node3:~$ sudo ceph health
2014-02-19 21:10:08.423410 7f80b2e10700  0 librados: client.admin authentication error (1) Operation not permitted
Error connecting to cluster: PermissionError
vagrant@node3:~$ sudo ceph auth list
2014-02-19 21:11:52.805005 7fd8c7dba700  0 librados: client.admin authentication error (1) Operation not permitted
Error connecting to cluster: PermissionError

If instead the error could be better worded and give a hint at the problem it would've helped. Like:

client.admin.keyring mismatch
Error connecting to cluster: PermissionError
