Includes MariaDB 5.5.36 and Galera
MariaDB Galera Cluster 5.5.36 includes MariaDB 5.5.36 with Codership additions
(lp:codership-mysql/5.5
till revision 3961
) and
Galera 25.3.2.
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 both 25.3.x and 25.2.x wsrep providers are available on the downloads page.
See the MariaDB 5.5.36 Release Notes and Changelog for more information on the changes in MariaDB.
Important : While upgrading the nodes of a MariaDB Galera cluster care must be
taken when using different versions of Galera library (wsrep provider). A
MariaDB Galera cluster node with Galera version 3 (25.3.xx) might fail to join
an existing cluster running with Galera 2 (25.2.xx) nodes. This happens due to
difference in the default values of 'socket.checksum' for Galera 2 and Galera 3
libraries.
So, in order to fix this, the node with Galera 3 should be started
with an additional wsrep provider option: socket.checksum=1
(e.g.
--wsrep_provider_options='socket.checksum=1; [other provider options; ...]'
) in
order to make it backward compatible with nodes running with Galera 2.
