It seems that you have not set the wsrep_provider in your server configuration. This is a mandatory setting. Most likely you will not have a working cluster right now. More information about setting up MariaDB Galera Cluster: https://mariadb.com/kb/en/mariadb/documentation/replication/galera/getting-s... Example configuration of wsrep_provider settings from /etc/my.cnf.d/server.cnf: wsrep_provider=/usr/lib64/galera/libgalera_smm.so ' Of course, you will need to have galera installed, which is available via the MariaDB yum and apt channels: https://downloads.mariadb.org/mariadb/repositories/ Kind regards, Pim Rupert
Tim - MariaDB 10.1 has merged Galera to the core server. 2014-11-11 15:40 GMT+02:00 Tim Callaghan <tmcallaghan@gmail.com>:

Sure, but if it's disabled by default I wouldn't expect to see a bunch of messages in my server's error log or have it shown in the server's banner. On Wed, Nov 12, 2014 at 11:24 PM, Laurynas Biveinis < laurynas.biveinis@gmail.com> wrote:
