Notes

  • Compatibility: Wsrep providers (Galera libraries) other than version 25.x.xx are not supported.
  • New: This release includes an new method for snapshot state transfer, wsrep_sst_xtrabackup-v2. This method of state snapshot transfer can be configured using --wsrep_sst_method=xtrabackup-v2 option. Its use would require Xtrabackup (>= 2.1.6) and other software packages like socat, nc, tar.
  • Note: Completely uninstall broken/partially installed 10.0.7-galera deb packages prior to installing this version, as they may conflict with 10.0.10-galera packages.

See the MariaDB 10.0.10 Release Notes and Changelog for more information on the changes in MariaDB.

Note: If Galera v2 and v3 are both being used in the cluster, MariaDB with Galera v3 must be started with wsrep_provider_options='socket.checksum=1' in order to make it backward compatible with Galera v2.
