Deleting a Read Replica¶
Scenarios¶
You can manually delete read replicas on the Instances page.
Important
Deleted read replicas cannot be restored. Exercise caution when performing this operation.
Constraints¶
You can delete read replicas only when the DB instance has two or more than two read replicas. A GaussDB(for MySQL) DB instance must have at least one read replica.
DB instances cannot be deleted when operations are being performed on them. They can be deleted only after the operations are completed.
Procedure¶
Log in to the management console.
Click
in the upper left corner and select a region and a project.Click Service List. Under Database, click GaussDB.
On the Instances page, click the target DB instance.
At the bottom of the Basic Information page, locate the read replicas to be deleted and choose More > Delete in the Operation column.
For high availability reasons, the system reserves an available read replica. The read replica cannot be deleted until the associated DB instance is deleted.
In the displayed dialog box, click Yes. Refresh the Instances page later to check that the deletion is successful.
