Brem,

When I try to restart rgmanager on all the nodes, this time i do not
see rgmanager running on the first node. But I do see on other 2
nodes.

Log on the first node:

Sep 28 18:13:58 cvtst1 clurgmgrd[24099]: <notice> Resource Group
Manager Starting
Sep 28 18:17:29 cvtst1 rgmanager: [24627]: <notice> Shutting down
Cluster Service Manager...
Sep 28 18:17:29 cvtst1 clurgmgrd[24099]: <notice> Shutting down
Sep 28 18:17:39 cvtst1 clurgmgrd[24099]: <notice> Shutdown complete, exiting
Sep 28 18:17:39 cvtst1 rgmanager: [24627]: <notice> Cluster Service
Manager is stopped.
Sep 28 18:17:40 cvtst1 clurgmgrd[24679]: <notice> Resource Group
Manager Starting

-
It seems service is running ,  but I do not see rgmanger running using clustat


Don't know what is going on.

Thanks
Paras.
