Galera cluster maintenance

ops-galera-remove.rst ops-galera-start.rst ops-galera-recovery.rst

Routine maintenance includes gracefully adding or removing nodes from the cluster without impacting operation and also starting a cluster after gracefully shutting down all nodes.

MySQL instances are restarted when creating a cluster, when adding a node, when the service is not running, or when changes are made to the /etc/mysql/my.cnf configuration file.
