Thanks Mr.Dubroski. I read something about STONITH. I make to you a question:

When the node A STONITH to node B, the node B is rebooted. When the node B has be rebooted, node B do not start the resources again?

I can to specify with "contraints" that the node with less score is the node to kill, the node will die?

I need that only the node with the best score keep the resources up. But if the nodes have not comunication between them, Who is responsible for selecting one of them to be active?
