Scaling Up Master Node Specifications

Updated at: Apr 28, 2020 GMT+08:00

As users' increasing services lead to Core node scale-out and high CPU usage, Master node specifications cannot meet user requirements and need to be scaled up. This section describes how to scale up Master node specifications. Note that Master node specifications can be scaled up only for clusters with the cluster HA function enabled.

Procedure (for MRS 1.8.2 or Later)

  1. Log in to the MRS management console.
  2. In the left navigation pane, choose Clusters > Active Clusters, select the cluster for which you want to scale up Master node specifications, and click its name to switch to the cluster details page.
  3. On the Nodes tab page, select Scale Up Specifications in the Operation column of the Master node group. The Scale Up Master Node Specifications page is displayed.
  4. Select the target specifications and click Submit Order. The order has been submitted successfully.

    The node specifications scale-up takes some time. After the scale-up is successful, the cluster status changes to Running.

    The VM to be scaled up is automatically stopped during the scale-up and started after the scale-up is complete.
