ocf::heartbeat:IPaddr2 FAILED
Two nodes, alice and bob that are set up to be redundant load balancers using
HAProxy. There are two floating IP address resources that need to be on the
machine for HAProxy to bind to (so only one machine will be running the HAProxy
resource at a time). Both machines are x86_64 CentOS 6.1 running corosync 1.4.1
and pacemaker 1.1.6.
alice.example.com = 172.16.32.10/24 (eth1)
bob.example.com = 172.16.32.11/24 (eth1)
