Hi ceph-users and ceph-devel, I came across an issue after restarting monitors of the cluster, that authentication fails which prevents running any ceph command. After we did some maintenance work, I restart OSD, however, I found that the OSD would not join the cluster automatically after being restarted, though TCP dump showed it had already sent messenger to monitor telling add me into the cluster. So that I suspected there might be some issues of monitor and I restarted monitor one by one (3 in total), however, after restarting monitors, all ceph command would fail saying authentication timeout… 2014-01-14 12:00:30.499397 7fc7f195e700 0 monclient(hunting): authenticate timed out after 300 2014-01-14 12:00:30.499440 7fc7f195e700 0 librados: client.admin authentication error (110) Connection timed out Error connecting to cluster: Error Any idea why such error happened (restarting OSD would result in the same error)? I am thinking the authentication information is persisted in mon local disk and is there a chance those data got corrupted?
