    The script galera_new_cluster is used to bootstrap new Galera Cluster,
    when all the nodes are down. Run galera_new_cluster on the first node only.
    On the remaing nodes simply run 'service rh-mariadb101-mariadb start'.

    For more information on Galera Cluster configuration and usage see:
