Hi! I still have the same problem with "Error initializing cluster client: Error" on all monitor nodes: root at bastet-mon2:~# ceph -w Error initializing cluster client: Error root at bastet-mon2:~# ceph --admin-daemon /var/run/ceph/ceph-mon.2.asok mon_status { "name": "2", "rank": 1, "state": "peon", "election_epoch": 1566, "quorum": [ 0, 1, 2], "outside_quorum": [], "extra_probe_peers": [], "sync_provider": [], "monmap": { "epoch": 3, "fsid": "fffeafa2-a664-48a7-979a-517e3ffa0da1", "modified": "2014-06-19 18:16:01.074917", "created": "2014-06-19 18:14:43.350501", "mons": [ { "rank": 0, "name": "1", "addr": "10.92.8.80:6789\/0"}, { "rank": 1, "name": "2", "addr": "10.92.8.81:6789\/0"}, { "rank": 2, "name": "3", "addr": "10.92.8.82:6789\/0"}]}} root at bastet-mon2:~# ceph --admin-daemon /var/run/ceph/ceph-mon.2.asok quorum_status { "election_epoch": 1566, "quorum": [ 0, 1, 2], "quorum_names": [ "1", "2", "3"], "quorum_leader_name": "1", "monmap": { "epoch": 3, "fsid": "fffeafa2-a664-48a7-979a-517e3ffa0da1", "modified": "2014-06-19 18:16:01.074917", "created": "2014-06-19 18:14:43.350501", "mons": [ { "rank": 0, "name": "1", "addr": "10.92.8.80:6789\/0"}, { "rank": 1, "name": "2", "addr": "10.92.8.81:6789\/0"}, { "rank": 2, "name": "3", "addr": "10.92.8.82:6789\/0"}]}} root at bastet-mon2:~# ceph --admin-daemon /var/run/ceph/ceph-mon.2.asok version{"version":"0.80.1"} ///////////////////////////////// The same situation on all 3 monitor nodes, but the cluster is alive and all clients works fine. Any ideas how to fix this? Pavel.
