I incline to ask you describe your use case a little bit more. Without knowing
it well, my view might be not fit you.

csync2 is often used by ClusterLabs community. But it is an individual tool,
and is not part of pacemaker. https://github.com/linbit/csync2

However, you refers to /etc/exports. I guess your use case is High Available
NFS? If so, you could leverage `man ocf_heartbeat_exportfs`. But this resource
agent doesn't use /etc/exports at all.

Roger
