  3. On the Cluster List page, click More at the right of the cluster that you want to expand and then select Expand from the list.


  4. Configure the specifications of the new node in the dialog box.

    You can select the number and the specifications of the ECS instances you are about to add to the cluster.

  5. Click Expand.
