'Galera cluster with 4 mysql nodes and 3 arbitrators

I have a Galera cluster with Geo-redundancy setup. First site : 2 Mysql nodes and 1 arbitrator Second site : 2 Mysql nodes and 1 arbitrator Third site : only one arbitrator.

  1. My First question is , in my.cnf file of each mysql node we have wsrep_cluster_address="" Above parameter should have all IP addresses listed ( like MYSQL nodes as well as 3 arbitrators IPs) right ? Is it correct ?
  2. My second question is , in file /etc/sysconfig/garb of each arbitrator, we have GALERA_NODES="" Above parameter should have IPs of only MYSQL nodes ?or it should have MYSQL nodes as well as remaining 2 arbitrator IPs( excluding itself) Please let me know.
