Scaling Up Storage Space

Scenarios

Constraints

• DB instances can be scaled up numerous times.
• The maximum allowed storage is 4,000 GB. There is no limit on the number of scale-ups.
• For primary/standby DB instances, scaling up the primary DB instance will cause the standby DB instance to also be scaled up accordingly.
• You cannot reboot or delete a DB instance that is being scaled up.
• Storage space can only be scaled up.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Database, click Relational Database Service.
4. On the Instances page, locate the target DB instance and choose More > Scale Storage Space in the Operation column.

   Alternatively, click the read replica name to go to the Basic Information page. In the Storage Space area, click Scale Storage Space.

5. On the displayed page, specify the new storage space and click Next.

   The minimum start value of each scaling is 10 GB. A DB instance can be scaled up only by a multiple of 10 GB. The allowed maximum storage space is 4,000 GB.

6. Confirm specifications.
   • If you need to modify your settings, click Previous.
   • If you do not need to modify your settings, click Submit.

7. View the scale-up result.

   Scaling up storage space takes 3-5 minutes. During this time period, the status of the DB instance on the Instances page will be Scaling up. After a while, click the DB instance and view the new storage space on the displayed Basic Information page to verify that the scale-up is successful.
