Yes, it is not supported in multi-site, and the behavior of CSV is weird in this scenario: on non-owning node, any process that tries to access CSV, just hangs and it does not start responding until you move CSV ownership to this node.

Reason for this is that DCM computes the topology between nodes according the static information in cluster configuration: it searches for cluster network that has both owning and non-owning node's NIC connected. In case it does not find such network, it mounts the CSV in something like 'Paused' state, so any calls through CSV driver to CSV will end in CSV driver waitng for volume to be ready....

In my opinion, this is not what product team exactly wanted - seems to me that CSV design was done not considering multi-subnet scenarios at all...
