I have setup 2 Node ( MySQL) Percona XtraDB cluster using instructions given on Percona site.  
For 3rd, I want to use garbd ( Galera Arbitrator).

[url][http://galeracluster.com/documentation-webpages/arbitrator.html[/url]](http://galeracluster.com/documentation-webpages/arbitrator.html%5B/url%5D)

What is --group=

Is it name of wsrep\_cluster\_name=mysql\_cluster in my.cnf ?

and also address , do I need specify MySQL 2 Node Cluster IP like in wsrep\_cluster\_address in my.cnf  
garbd --group=example\_cluster [COLOR=#4070A0][B][/B] --address=“gcomm://192.168.1.1,192.168.1.2,192.168.1.3”  
Any input is greatly appreciated. Thanks
