[Linux-cluster] Two-node clusters in split-sites

we are planning to run two-node clusters (for database and
file-services) with cluster nodes in different sites with a fast, but
sometimes unreliable network connection. Data should be replicated with
DRBD between the cluster nodes/sites (no shared storage).
I'm specially afraid of split brain here. In this scenario fencing
depends on the (unreliable) network connection between the two sites -
in my opinion fencing is unreliable and not possible in this scenario.
What would be the best way to run such a cluster?
