Storage Space

Scenarios

This section describes how to scale storage space of an instance to suit your service requirements.

Precautions

• Storage space of an instance can be scaled up or down.
• When the disk usage of a GeminiDB Redis instance exceeds 95%, the instance enters the read-only mode. You can only read or delete data from the instance, but cannot write new data into it. To keep services accessible, scale up storage space when the disk usage exceeds 80%.
• When you scale down storage space of your instance, make sure that new storage space is 25% more than the used space and rounded up.
• Storage scaling does not interrupt your services. After storage scaling is complete, you do not need to restart your instance.
• To view storage details on the Instances page, contact customer service.

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

   • For yearly/monthly instances
     • If you need to modify your settings, click Previous.
     • If you do not need to modify your settings, click Submit and complete the payment.
   • For pay-per-use instances
     • If you need to modify your settings, click Previous.
     • If you do not need to modify your settings, click Submit.

7. Check the scaling result.
   • When the scaling task is ongoing, the instance status is Scaling storage space.
   • After the scaling task is complete, the instance status becomes Available.
   • In the Storage Space area on the Basic Information page, view the new storage space.

Method 2

1. Log in to the management console.
2. In the service list, choose Databases > GeminiDB Redis API.
