Hmm, I think DRBD is only advised in cases where the net link between
the replicated boxes is guaranteed and low-latency; so I guess probably
this is not a working solution between different data centers as
discussed here.
However, I can't suggest alternatives, I am afraid...
My instinct (though not always correct :-) ) tells me also that
near-real-time file sync (like using lsyncd with rsync) should not be a
suggested solution for queue replication.
One could investigate whether Apache Helix (http://helix.apache.org/)
can be a viable solution.
All the best,
