I am trying to set up a split-site clustering with Pacemaker. Each site is likely be served by a different ISP and plan is to have N-M config with 20 active nodes and 2 passive nodes. In the event of a failover, data needs to be replicated over to the new active node. The clients will be configured with a single IP address(a set of clients per each active node) and will have to stay that way. Basically, the failover should be seemless for the clients. I am not clear on how the IP addressing would work and how to configure this setup.
Is this possible with Pacemaker. I have seen documentation about split-site supported by Pacemaker. However, it is not clear if the nodes need to be part of the private network connected by fiber links or something.
