Note

After making changes in a management node's configuration, it is necessary to perform a rolling restart of the cluster in order for the new configuration to take effect. See Section 17.3.2.4, “Defining a MySQL Cluster Management Server”, for more information.

To add new management servers to a running MySQL Cluster, it is also necessary perform a rolling restart of all cluster nodes after modifying any existing config.ini files. For more information about issues arising when using multiple management nodes, see Section 17.1.5.9, “Limitations Relating to Multiple MySQL Cluster Nodes”.
