<pre wrap="">I'm trying to setup a colocation rule so that a couple of master-slave
resources cant be master unless another resource is running on the same
node, and am getting the exact opposite of what I want. The master-slave
resources are getting promoted to master on the node which this other
resource isnt running on.
In the below example, 'stateful1:Master' and 'stateful2:Master' should
be on the same node 'dummy' is on. It works just fine if I change the
colocation around so that 'dummy' depends on the stateful resources
being master, but I dont want that. I want dummy to be able to run no
matter what, but the stateful resources not be able to become master
without dummy.

<pre wrap="">
use dummy:Started ... default is to use same role as left resource, and
Dummy will never be in role Master ...

Tried that too (just not the configuration at the time I sent the
email), no effect.<br>
