[ClusterLabs] IPaddr2 cluster-ip restarts on all nodes after failover

[Joakim Hansson]

Hi list!
I'm running a 3-node vm-cluster in which all the nodes run Tomcat (Solr)
from the same disk using GFS2.
On top of this I use IPaddr2-clone for cluster-ip and loadbalancing between
all the nodes.

Everything works fine, except when i perform a failover on one node.
When node01 shuts down, node02 takes over it's ipaddr-clone. So far so good.
The thing is, when I fire up node01 again all the ipaddr-clones on all
nodes restarts and thereby messes up Tomcat.

Here is my configuration:

 node01 node02 node03
