I noticed that MariaDB Galera 5.5.33a starts with binlog_format=STATEMENT (when started with wsrep settings, that is as galera node).
As far as I know it is not supported by Galera.
Noticed for instance that deleting from an empty table gives an error:
MariaDB [test]> delete from my_table;
ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction
Is it correct to start a galera node with binlog_format=ROW ?
