Hi, I am looking into using your facilities to have high availability on my system. I am trying to figure out some things. I hope you guys could help me. I am interested in knowing how pacemaker migrates a VIP and how a splitbrain situation is address by your facilities. To be specific: I am interested in the following setup:
2 linux machines. Each machine runs a load balancer and a Tomcat instance. If I understand correctly pacemaker will be responsible to assign the main VIP to one of the nodes. My questions are: 1)Will pacemaker monitor/restart the load balancers on each machine in case of crash? 2) How does pacemaker decide to migrate the VIP to the other node? 3) Do the pacemakers in each machine communicate? If yes how do you handle network failure? Could I end up with split-brain? 4) Generally how is split-brain addressed using pacemaker? 5) Could pacemaker monitor Tomcat? As you can see I am interested in maintain quorum in a two-node configuration. If you can help me with this info to find a proper direction it would be much appreciated!
