    Due to the fact that the process of rebalancing the data is quite tricky, it is not really feasible to add the data node to the NDB cluster in ClusterControl. The recommended way would be to deploy a new cluster with a correct number of data nodes, provision it with data, setup the replication between the old and the new one and, eventually, switch the traffic to the new, larger cluster.
