Hi Colin /var/run/ceph exist on only one node(the node on which i start the cluster with -a) But ceph is running on all nodes(checked with ps -ef) When i ssh into nodes and try to stop osd (/etc/init.d/ceph stop osd) it does not work(this was my second issue) But when i stop /etc/init.d/ceph -a stop ,it stops ceph of that node.
