Wow, Brian, thanks for such a speedy reply. Regarding: > > 2. Must I create and bring up an aliased IP on node 1? Heartbeat will create the IP address your haresources file should look something like: alpha IPaddr::192.168.5.2/24/eth0 As to the IP address in haresources, it must be of the same subnet as the two nodes, right? As in: node 1 192.168.100.12/22 node 2 192.168.100.6/22 node 1 IPaddr::192.168.103.6/22/eth0 (Of course, the CIDR 22 means that my netmask is 255.255.252.0, giving my LAN addresses 102.168.100.0 - 192.168.103.255). Also, is the construct IPaddr::192.168.103.6/22/eth0 correct? I'm not meaning to question you, but I've not seen it written like that in any of the stuff I've read. Again, thanks.
