Scaling Up Storage Space

Scenarios

This section describes how to scale up the storage space of a DB instance to suit your service requirements.

Storage scaling does not interrupt your services. After storage scaling is complete, you do not need to restart your instance.

Precautions

• Storage space can only be scaled up.
• To view storage details on the Instances page, contact customer service.
• When the total storage space is greater than or equal to 600 GB and the available space (total storage space – used storage space) is less than 18 GB, the instance is read-only. After the available space is scaled up to 90 GB or more, the instance becomes available.
• When the total storage space is less than 600 GB and the space usage (used space/total space) is greater than or equal to 97%, the instance is read-only. When the storage usage after scaling drops to 85% or lower, the instance becomes available.

Method 1

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Influx API.
3. On the Instances page, locate the instance whose storage space you want to scale up and click its name.
4. In the Storage Space area on the Basic Information page, click Scale.

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

   Select at least 1 GB each time you scale up the storage, and the storage size must be an integer.

6. On the displayed page, confirm the storage space.
   • For yearly/monthly instances
     • If you need to modify the settings, click Previous.
     • If you do not need to modify the settings, click Submit and complete the payment.
   • For pay-per-use instances
     • If you need to modify the settings, click Previous.
     • If you do not need to modify the settings, click Submit.

7. Check the scaling-up result.
   • When the scale-up task is ongoing, the instance status is Scaling up.
   • After the scale-up task is complete, the instance status becomes Available.
   • In the Storage Space area on the Basic Information page, check whether the scale-up is successful.

Method 2

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Influx API.
3. On the Instances page, locate the instance whose storage you want to scale up and choose More > Scale Storage Space in the Operation column.
