Same here...

As far as I can tell set_drbdsetup_props() looks okay. The problem is that we
are not able to reproduce your problem. In a drbdmanage environment[1]
everything looks fine, both nodes are able to switch the resource to primary
(tested with 'drbdadm primary' on both sides)...

Is it reproducible? Even if you start from scratch (drbdmanage unit)?
