I want to run some script (pacemaker configuration, to be precise) on one node of a cluster. This node have to be both online pacemaker node and one of the nodes with this configuration resource (or at least with same recipe this resource defined in). Current version selects node to run the code as first online node of the cluster, but it don't know whether the code will run on that node. What would you suggest me to do?
