@janlindstrom I'm sorry but you are wrong.
"In MariaDB 10.1 the MariaDB Server and MariaDB Galera Server packages have been combined and Galera packages and their dependencies get installed automatically when installing MariaDB. The Galera parts remain dormant until configured, like a plugin or storage engine." - https://mariadb.com/kb/en/mariadb/getting-started-with-mariadb-galera-cluster/
