percona xtradb cluster add new nodes

Dear Percona,

Now our company (intelix.co.id) try to using percona xtradb cluster as database server.

I see the tutorial on URL https://www.percona.com/doc/percona-xtradb-cluster/5.6/howtos/centos_howto.html

There are some question for you :

  1. Why need three nodes for “percona xtradb cluster”, whatis the reason?

  2. I just setup two nodes server “percona xtradb cluster” and already working, my question :

  • If i want to add new node so it three nodes , how about the steps?

  • If one node fails (example : server crash) how can add new node?

  1. Is it “percona xtradb cluster” support innodbbackup?
