Running a single cluster across different LANs with an unreliable
network connection doesn't seem like a situation supported by
Pacemaker. You probably need to look at something like booth [1] to get
this to work reliably.

Booth allows resources to migrate between different clusters, using
tickets and an arbiter in a third location.
