Hi AW Did you check on firewall ( iptables ) between the nodes. If this is a test cluster disable iptables and try.

I assume that it is because I tried to add a second monitor which seemed to hang during the “hunting” phase. I eventually had to kill the tasks which I think resulted in my monmap becoming corrupt. I have tried to access it from the only remaining working monitor, but have not had much joy with that. I have also tried to follow the docs re removing monitors from unhealthy clusters, but have as yet had no luck with getting the stable monmap extracted.... When I run any ceph command from the remaining monitor host I get the following error: 2013-10-30 14:19:01.822660 7f16080f2700 -1 monclient(hunting): ERROR: missing keyring, cannot use cephx for authentication 2013-10-30 14:19:01.822743 7f16080f2700 0 librados: client.admin initialization error (2) No such file or directory Error connecting to cluster: ObjectNotFound It’s the hunting part which implies that something is still stuck from when I tried to add the second monitor. Any ideas on how I can fix the monmap so the remaining monitor can be used again?
