You could probably trivially extend central_processing mode to do "anti collocation" (i.e. run on another node). The 'follow_service.sl' script is an example of how to do part of 'anti-collocation'. The way it works, it starts service A on a different node from service B. If the node running service A fails, it is started on the same node as service B, then service B is moved away to another (empty, usually) node in the cluster. Alternatively, pacemaker supports this functionality. -- Lon Hohberger - Red Hat, Inc. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
