Editing Logical Clusters

  1. Log in to the GaussDB(DWS) console. In the navigation pane, choose Clusters > Dedicated Clusters.
  2. In the cluster list, click the name of the target cluster. The Cluster Information page is displayed.
  3. In the navigation pane, choose Logical Clusters and click Edit in the Operation column of the target cluster.

  4. Add a node to the logical cluster by moving the selected ring from the right to the left, or remove a node from the logical cluster by moving the selected ring from the left to the right, and click OK.

  5. When adding a node, select online or offline scale-out as needed.

  • Nodes are added to or removed from a logical cluster by ring.
  • At least one ring must be reserved in a logical cluster.
  • The ring removed from the logical cluster will be added to the elastic cluster.
  • Logical clusters of version 8.1.3 and later support online scale-out.
