This topic describes how to repair and rebuild nodes for a MyBase on ACK instance.
Prerequisites
You must stop the node before you can repair or rebuild it. For more information about how to stop a node, see Start and stop a node.
Usage notes
Repairing a node starts the node and adds it back to the primary/secondary topology.
Procedure
Log on to the ApsaraDB for MyBase console.
In the upper-left corner of the console, select a region. Find the cluster that you want to manage and click the cluster ID to go to the cluster management page.
In the left-side navigation pane, click Instances.
Find the instance that you want to manage and click the instance ID to go to the Basic Information tab of the instance.
In the Database Engine Nodes section, click Operations in the lower-right corner of the target secondary node's card, and select Try to Repair or Rebuild Node as needed.
In the dialog box, click OK.
After a successful repair or rebuild, the node starts automatically.
