Enabling Storage Autoscaling for a FlexusRDS Instance

Scenarios

With storage autoscaling enabled, when FlexusRDS detects that you are running out of database space, it automatically scales up your storage.

Constraints

• If your account balance is insufficient, storage autoscaling will fail.
• The storage space can be autoscaled up only when your instance status is Available or Storage full.
• For a primary/standby DB instance, autoscaling the storage for the primary node will also autoscale the storage for the standby node.
• If a yearly/monthly DB instance has pending orders, it will not be autoscaled.

Procedure

1. In the instance list, click the target instance name.
2. On the Overview page, click Configure under the Configure Autoscaling field.
3. In the displayed dialog box, click and configure the required parameters.
