Fresh Install Ubuntu1604, All (3) nodes report cluster size of 1

Morning everyone…

As the title suggests, I’m having some difficulty getting this running. I have followed the installation instructions, and various other resources I’ve found.

My issue is that after bootstrapping the first node (show status like ‘wsrep%’; shows a cluster size of 1) and then starting mysql on the other 2 nodes, all 3 nodes report “wsrep_cluster_status Primary” and “wsrep_cluster_size 1”

Can anyone help with getting this going, happy to provide whatever information will help!
