Thanks Lars, that makes senses. So, to start and stop a master/slave resource, do you recommend adding target_role=stopped to stop it, and deleting target_role altogether to start it? And, should the nvpair for target_role be at the master_slave tag level or at the primitive (i.e. rsc_drpd_7788:0, etc) tag level?
One other thing, did you see the question I raised about the Place constraint I've been using? I have one defined against the drbd master_slave resource ID, and the question was whether this was the right resource, or should I make the constraint against postgres? And if against postgres, how does the preference for a particular node get communicated from the group postgres is in back to the drbd master_slave resource?
