It's taken me a while to twig what the "Clusters" interface actually does in StarWind v8, i.e. it's primarily a visual/user interface layer on top of the replication between servers. Specifically, you can remove a cluster and HA carries on working... all you've done is remove the management console's knowledge of the cluster from a visual POV plus the ability to use the create-cluster wizard.
I came across this realisation when I wanted to change the sync network configuration on the cluster. There isn't a way to edit the cluster settings so one for the wishlist. At present, if you want to add (say) more NICS into your sync network for new storage, you have to remove the cluster and re-create it. Need a right-click/Properties option on the cluster name to allow the options specified in the attached screenshot to be edited.
Cheers, Rob.
