Compiling a newer corosync/pacemaker is a perfectly good solution in
this situation, but just to give you more options:
You could instead put the app inside a RHEL 6 container, and run it on
RHEL 7 cluster hosts. The advantage of that approach is that the rest
of your usual system services would be on more modern versions. With
bundles (available in the newer pacemaker on RHEL 7), you can use your
existing resource agent to launch the service inside the bundle, so the
cluster can monitor it (as well as monitoring the container itself).
Similarly, you could create a RHEL 6 VM and run it on RHEL 7 cluster
hosts. You can add the remote-node option to the VM resource, to be
able to launch and monitor the app inside it via its resource agent.
