It still boggles my mind, not being an expert though for a
while have 'pacemaker' run in my setups, how relationships
and dependencies between resource work.
I've had another resource which I preferred to hold to a
specific node and also colocation constraint where that
resource was to run with vIP of pgsqld
HA-10-3-1-226 with HA-10-1-1-226 (score:INFINITY)
HA-10-1-1-226 is pgsqld's
logic of that just brakes my mental health :)
So cancel and mark as non-existent the issue I originally
many thanks, L.
