Notes about this release
- MariaDB Galera Cluster 5.5.37 includes MariaDB 5.5.37 with Codership
3980) and Galera 25.3.5.
- This version of MariaDB Galera Cluster supports
wsrepAPI v25 which means MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x Galera
wsrepprovider. A 25.3.x
wsrepprovider is included in the MariaDB repositories and both 25.3.x and 25.2.x wsrep providers are available on the downloads page.
- This release includes a new method for snapshot state
wsrep_sst_xtrabackup-v2. This method of state snapshot transfer can be configured using the
--wsrep_sst_method=xtrabackup-v2option. Its use requires Xtrabackup (>= 2.1.6) and other software packages like socat, nc, and tar.
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.
Important: wsrep_sst_rsync (sst script) in MariaDB Galera Cluster 5.5.37 uses
lsof which might not be installed by default on some linux distributions. It has to be installed if the
wsrep_sst_method is set to
rsync (default). Future MariaDB Galera Cluster releases will address this by adding a dependency on lsof.
This release contains fixes for bugs, compiler errors/warnings and improvements in existing scripts.
A list of all the bugs fixed can be found in the changelog.
Thanks, and enjoy MariaDB Galera Cluster!
