With any failover/VIP setup there is always the possibility of a split-brain but for the most part I haven't seen this happen in my environment. Also, use IPaddr2 as the resource type as it will do an gratuitous arp, significantly decreasing the failover time. eg. [haresources file] node.fqdn IPaddr2::10.10.10.10/24/eth1 Substitute your IP, mask and network interface. There are some options you can set as well that tell it not to fail back automatically, just so you can check the box that failed before pushing services back to it. Tait
