Mutually Exclusive DR Cases

Case 1: How Do I Scale out a Cluster in the DR State?

1. Log in to the GaussDB(DWS) management console.
2. In the navigation pane on the left, click Clusters.
3. In the cluster list, if Task Information of the cluster you want to scale out is DR not started, perform 5 and 7.
4. If the Task Information is other than DR not started, delete the DR task. For details, see Deleting DR Tasks.
5. In the Operation column of the production and DR clusters, choose More > Scale Out.

6. Create a DR task. For details, see Creating a DR Task.
7. Start the DR task. For details, see Starting a DR Task.
   

   After scale-out, the number of DNs in the production cluster must be the same as that in the DR cluster.
