Updates and fixes in this version

  • This release is mainly a bug-fix release.
  • The Galera library used by MariaDB Galera Cluster and included in the MariaDB repositories is currently at version 25.3.9.
  • ALTER TABLE EXCHANGE PARTITION command was not getting replicated to other nodes in the cluster. (MDEV-7501)
  • GRANT/REVOKE role commands were not getting replicated to other nodes in the cluster. (MDEV-8434)
  • CREATE/ALTER VIEW commands were not replicated properly if ALGORITHM clause was missing. (MDEV-8464)
  • RENAME TABLE command was getting replicated and executed on other nodes even when the user did not have sufficient privileges. (MDEV-8598)


  • Running MariaDB Galera Cluster 5.5 and 10.0 nodes in a cluster is not supported (MDEV-6257)
  • This version of MariaDB Galera Cluster supports wsrep API v25 which means MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x Galera wsrep provider. A 25.3.x wsrep provider is included in the MariaDB repositories and is also available from the downloads page.
  • On Ubuntu and Debian, the Galera Arbitrator daemon (garbd) and the galera library are in two separate packages. The packages are named galera-3 and galera-arbitrator-3. When installing MariaDB Galera Cluster on Ubuntu and Debian (the mariadb-galera-server package), the galera-3 package will be automatically installed. You can then install the arbitrator package on a separate node (recommended) or on one of the nodes running mariadb-galera-server (not recommended).

Note: If Galera 25.2.x and 25.3.x are both being used in the cluster, MariaDB with Galera 25.3.x must be started with wsrep_provider_options='socket.checksum=1' in order to make it backward compatible with Galera v2. Galera wsrep providers other than 25.3.x or 25.2.x are not supported.

Thanks, and enjoy MariaDB Galera Cluster!
