Scaling Up Master Node Specifications

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.

Prerequisites

You have checked whether the Host Security Service (HSS) is enabled. If HSS is enabled, disable the HSS monitoring on the MRS cluster before upgrading the Master node specifications.

Use Restrictions

Master nodes can be scaled up for clusters with two or more master nodes.
The specifications of the Master node in a BMS cluster cannot be upgraded.

Master Node Specification Upgrade (One-Click Upgrade)

Log in to the MRS console.
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.
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.
Select the target specifications and click Submit Order. The order has been submitted successfully.
The node specification 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.
- The scale-up does not automatically upgrade the memory of components due to different component usage requirements. You can adjust the memory of components as needed.
