They clearly should not. Rather than soliciting other people's
configurations and then try to adapt yours based on that, why don't you
upload _your_ CIB (not just a "crm configure dump", but a full "cibadmin
-Q") and your DRBD configuration to your pastebin/pastie/fpaste and let
people tell you where your problem is?

That setting is only evaluated by the drbd init script, which you're
probably not using as it's not required (nor beneficial) in a Pacemaker

And what did SUSE support have to say about this?
