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.
