[Linux-cluster] Not able to stop cman service

[Shailesh]

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.

Thanks & Regards
