we still use the heartbeat v1 style "drbddisk" "resource agent",
even with crm style heartbeat, because it tends to behave more
predictably than the "multistate drbd" resource agent.

drbd is loaded and configured by init,
role changes (secondary <-> primary)
are controlled by heartbeat using
the drbddisk script.  it just works.

if you want to go the "multistate" route, and use the "OCF" drbd
resource agent, make sure you use the very latest heartbeat and script.
it has been very much improved, I think, though I did not personally
look at this multistate resource stuff recently.
