I would think that your local Corosync doesn't like the fact that it's
the only Corosync instance configured to run with parameters different
from the other Corosync instances in the cluster.

What I always do when I need to make changes to the Corosync config is
enable Pacemaker maintenance mode, shut down pacemakerd & corosync on
all nodes, make the change, fire corosync & pacemakerd back up,
disable maintenance mode. I don't know how you would duplicate this in
puppet, or if that's even possible, but that would be my generally
recommended approach.

Cheers,
Florian
