In my configuration, I group the VM stonith agents with the corresponding VM resource, to make them move together[1]. Here is my use case: 1. Resource ONE-Frontend-Group runs on nebula1 2. nebula1 is fenced 3. node one-fronted can not be fenced Is there a way to say that the life on node one-frontend is related to the state of resource ONE-Frontend? In which case when the node nebula1 is fenced, pacemaker should be aware that resource ONE-Frontend is not running any more, so node one-frontend is OFFLINE and not UNCLEAN. Regards.
