To elaborate, use -INFINITY if you want the IPs to *never* run on the same node, even if there are no other nodes available (meaning one of them has to stop). If you *prefer* that they run on different nodes, but want to allow them to run on the same node in a degraded cluster, use a finite negative score. -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
