SCALE is intended to be a scale-out system, so has allowances for that in the design, but perhaps not exactly what you're looking for. Clusters really need 3 or more nodes to operate properly.

You can perhaps use glusterfs directly to establish a gluster volume on both sides which will replicate as per the settings you make when setting it up. (https://docs.gluster.org/en/main/Quick-Start-Guide/Quickstart/#step-5-configure-the-trusted-pool)

The official/supported way to do that is to build a cluster with your SCALE systems via TrueCommand. (although I've seen that it's not very well documented and/or quirky, so may not work well as yet... still rated as experimental) https://www.truenas.com/docs/truecommand/clusters/
