Your configuration is correct, but keep in mind scores of all kinds
will be added together to determine where the final placement is.

In this case, I'd check that you don't have any constraints with a
higher score preferring the other node. For example, if you previously
did a "move" or "ban" from the command line, that adds a constraint
that has to be removed manually if you no longer want it.

I'm confused. constraint from what I think means there's a preferred node.
But if I want my resources not to have a preferred node is that possible?
