I'm configuring Percona XtraDB Cluster 8 on two nodes, and use a 3rd node to act as an arbiter.
I cannot make up out of the docs whether to add the IP of the arbiter in the galera nodes addresses of the arbiter’s configuration.
# A comma-separated list of node addresses (address[:port]) in the cluster # GALERA_NODES=""
Also, do I add the IP of the arbiter in the
wsrep_clsuter_address of the Galera configuration? Again, it's not described in the docs.
