    Hi,

    Those two clusters are separate entities therefore wsrep_cluster_state_uuid should be different. Think of it as a two separate nodes (Galera cluster consisting of several nodes can be, to some extend, treated as a single entity) connected via replication. As such, obviously, your DR cluster will have to be started and provisioned using data from the primary site before you can configure the replication. Again, think as two nodes in a replication setup.

    Data replicated to slave node will be replicated to the rest of the cluster assuming you have log slave updates enabled. This should be enough to trigger the galera replication across the DR cluster.
