Funny, it works here.

Nope, it doesn't, but that'll certainly make your configuration rather big. Perhaps you can try with the asymmetric cluster (set symmetric-cluster to false). In that case you should get by with only the first two location constraints. But note that you will need location constraints for all rsc-node combinations when you want to allow the resource to run.
