Fellow clusterites, I have 2 node gfs-gnbd RHCS Cluster and I wanted to add third node to it. In the process , I have tried to stop the cman service in the existing nodes , the stopping fails. > service cman stop fails. Stopping cman: [FAILED] I tried the 'cman_tool leave' command it has also failed. > cman_tool leave Error: Can't leave cluster while there are 1 active subsystems The /proc/cluster/services file dump shows that 'usrm::manager' is running , so how do I stop this service?? Service Name GID LID State Code User: "usrm::manager" 2 3 run - [1 2] If you anything about this 'usrm::manager' please let me know.
