When a galera cluster is configured with wsrep_osu_method=TOI and wsrep_strict_ddl=ON it's not possible to alter or delete partitioned tables (You will get the error message ERROR 4165 (HY000): DDL-statement is forbidden as table storage engine does not support Galera replication.

However it's still possible to create partitioned tables with those settings.
This should be disallowed, as it doesn't make sense to have partitioned tables, when you can't alter them (eg when you want to run a reorganize of the table).
