Hi Joao, Thanks for replying. All of my monitors are up and running and connected to each other. "ceph -s" is failing on the cluster with following error: 2013-10-07 10:12:25.099261 7fd1b948d700 -1 monclient(hunting): ERROR: missing keyring, cannot use cephx for authentication 2013-10-07 10:12:25.099271 7fd1b948d700 0 librados: client.admin initialization error (2) No such file or directory Error connecting to cluster: ObjectNotFound
This says it all. You're somehow missing your keyring. Or maybe you're not but you're keeping it in a non-default location and you're not specifying a path to it either on your ceph.conf or via '--keyring <path>'.
And the logs on each monitor has lots of entries like this: NODE 1: 2013-10-07 03:58:51.153847 7ff2864c6700 0 mon.jul@0(probing).data_health(0) update_stats avail 76% total 42332700 used 7901820 avail 32280480 2013-10-07 03:59:51.154051 7ff2864c6700 0 mon.jul@0(probing).data_health(0) update_stats avail 76% total 42332700 used 7901832 avail 32280468 2013-10-07 04:00:51.154256 7ff2864c6700 0 mon.jul@0(probing).data_health(0) update_stats avail 76% total 42332700 used 7901828 avail 32280472
Those messages are simply reports on the mon store's storage capacity. -Joao

I am using RHEL 6.4 as OS with dumpling(0.67.3) release. Ceph cluster creation (using ceph-deploy as well as mkcephfs), ceph-creates-keys doesn't return on any of the servers. Whereas, if I create a cluster with only 1 node (1 monitor), key creation goes through. Has anybody seen this problem or any ideas what I might be missing?? Regards, Abhay Those symptoms tell me that your monitors are not forming quorum. 'ceph-create-keys' needs the monitors to first establish a quorum, otherwise it will hang waiting for that to happen. Please make sure all your monitors are running. If so, try running 'ceph -s' on your cluster. If that hangs as well, try accessing each monitor's admin socket to check what's happening [1]. If that too fails, try looking into the logs for something obviously wrong. If you are not able to discern anything useful at that point, upload the logs to some place and point us to them -- we'll then be happy to take a look. Hope this helps. -Joao -- Joao Eduardo Luis Software Engineer | http://inktank.com | http://ceph.com
