i’m a percona newbie. i have 3 nodes  
wsrep\_cluster\_address=gcomm://abc.112.0.1,abc.112.0.2,abc.112.0.3  
Does my my.cnf fie have to fill in all these 3 ips, or is this okay?  
node 1: wsrep\_cluster\_address=gcomm://  
node 2:wsrep\_cluster\_address=gcomm://abc.112.0.1,abc.112.0.2  
node 3:wsrep\_cluster\_address=gcomm://abc.112.0.1,abc.112.0.3  
wsrep\_cluster\_address=gcomm:// And how does this work?

It needs to look like this:  
wsrep\_cluster\_address=gcomm://abc.112.0.1,abc.112.0.2,abc.112.0.3  
on all 3 nodes.
