It's far more simple: if you retain the same hostname/ip address on
the new machine, you need to make sure the new glusterd has the same
UUID of the old dead one (there is a file in /etc/glusterd),
configurations are automatically synced back at the first contact with
the other active nodes.

Instead, if you replace the node with a different node with different
hostname / ip:
