Re: [Linux-cluster] rgmanager not running



The rgmanager service is not necessary if the cluster has no resources to manage....further more info on cluster status is needed like

#clustat


If it says all the nodes are online then more debug logs will be needed to find out the problem.

Subject: [Linux-cluster] rgmanager not running

Dear All,

I have using RHEL6 Linux and Kernel Version is 2.6.32-71.el6.i686

I have configured Cluster Suite with 2 servers Server 1 : 192.168.13.131 IP Address and hostname is primary Server 2 : 192.168.13.132 IP Address and hostname is secondary Floating : 192.168.13.133 IP Address (Assumed by currently active server)

I have verified that service cman is running and cluster.conf is valid using ccs_config_validate command

Finally i found that rgmanager is not running and services are not started [root primary cluster]# service rgmanager status rgmanager dead but pid file exists [root primary cluster]# [root primary cluster]# cman_tool services [root primary cluster]# [root primary cluster]# cman_tool status
