As you already have a SAN I'm wondering why you want to use
DRBD at all.

Sure I don't know all requirements in the given situation, but
wouldn't it be sufficient to have one LUN with proper zoning
for the cluster nodes? To avoid a SPOF you should apply best
practice solutions like redundant FC controllers, switches,
multipathing, etc. anyway.

With a SAN-only design performance would be way better than
with DRBD on top of it. It's also easier and less risk for
the admin to have one layer less to configure and maintain.

Just my 2 euro-cents...
