I can't find much documentation for no-quorum-policy. I need the
cluster to keep working in case the connections between the two
datacenters are cut. It should be impossible (or very nearly
impossible) for both sides to have the clustered resource up. This is
for a drbd+nfs+ip setup.

no-quorum-policy doesn't seem to help with the split brain situation does it?

Is this like ocfs2? Each node locks a journal, and if it can't lock
the journal its kernel panics? Leaving the cluster would be better
here. Where can I read about this?
