[Pacemaker] nodes in different network

[Herbert Monteiro]

Hi all,

I want high availability in my server. My server run many tools
(apache, eXist and other applications developed by myself). To do the
HA I buy another server and install that same tools. My problem is
that the servers are in different networks and when the node 1 failure
the node 2 should take the same DNS name (e.g. node 1 failure => node
2 detect => node 2 take on the same FQDN  of the node 1 => node 2 run
all applications).

To solve the same FQDN problem I think in enable a Dynamic Zone for
these servers in my DNS. The Node 1 at intervals update the DNS with
x.x.x.x = > server.myzone.com. The node 2 when detect the node 1
failure update the DNS with y.y.y.y => server.myzone.com. But I saw
that the pacemaker (corosync configuration) use the broadcast to
lookup other nodes, but in my scenario it isn’t possible.
How Can I use the pacemaker in this case?

thanks
