How Do I Do If the GaussDB(DWS) Scale-Out Check Fails?

Symptom

After you click OK during scale-out or adding idle nodes, a warning message is displayed and you cannot go to the next step.

Cause Analysis

Before submitting a scale-out task, the system checks items such as resource quotas and IAM permissions. Abnormal items will stop scale-out tasks from being submitted to prevent scale-out failures.

Solution

  • IAM permissions: This problem occurs when a user has only an IAM account. In this case, permissions such as VPC and EVC/BMS permissions need to be assigned to the IAM account. Or, the user can use the master account to perform scaling out.
  • If there are no abnormal items but the dialog box still exists, contact technical support.
