The documentation could be clarified ...

Each *_uname variable lists the nodes that the corresponding *_resource
entries are running on. Since inactive resources aren't running on any
node, that's the only *_resource variable that doesn't have a matching
*_uname.

In other words, inactive_uname would not be a list of inactive nodes,
nor a list of nodes not running the inactive resources, it would be a
list of nodes running the inactive resources.
