I still can't understand why the whole cluster will fail when only 3 nodes are down and a qdisk is used.
CityA -> 3 nodes to run packageA -> 3 votesCityB -> 3 nodes to run packageB -> 3 votesCityC -> 1 node which cannot run any package (qdisk) -> 1 vote

As long as one city is up + qdisk -> your cluster will be working.
Then you just configure that packageA cannot run in CityB, packageB cannot run in CityA.If all nodes in a city die, the relevant package will be down.
Last, you configure your last resource without any location constraint.
PS: by package consider either a resource group or a single resource.
