When deploying a new HA overcloud, the mysql/galera service can now be
|
|
configured to use mariabackup for State Snapshot Transfers (SST) by
|
|
configuring the new Heat parameter `MysqlGaleraSSTMethod`. Mariabackup
|
|
SST uses a dedicated SQL user with the appropriate grants to transfer
|
|
the database content across nodes. The user credentials can be
|
|
configured via two additional Heat parameters `MysqlMariabackupUser`
|
|
and `MysqlMariabackupPassword`.

|
|
The new support for mariabackup SST for the mysql/galera service is
|
|
currently limited to new overcloud deployments. Doing a stack update
|
|
to change SST method from rsync to mariabackup or the other way around
|
|
is currently not supported.
