Manually Scaling Up Storage Space

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

Usage Notes

  • Storage space can only be scaled up.
  • You do not need to restart the instance while scaling its storage. The change has no impact on existing data, services, or your databases.

Read-only Instance

To maintain stability when storage is about to be exhausted, your GeminiDB DynamoDB-Compatible instance will become read-only, and its data cannot be modified. If this happens, you can scale up the storage to restore the instance status.

Storage

Description

< 16,000 GB
  • When the storage usage reaches 97%, the instance becomes read-only.
  • When the storage usage decreases to 85%, the instance exits the read-only mode.

≥ 16,000 GB
  • If the remaining storage is less than 480 GB, the instance becomes read-only.
  • When the remaining storage is greater than or equal to 2400 GB, the instance exits the read-only mode.

Instances with classic storage are not read-only.

Procedure

  1. Log in to the Huawei Cloud console.
  2. On the Instances page, locate the target instance and choose More > Scale Storage Space in the Operation column.

    Click the instance name. In the Storage Space area on the Basic Information page, click Scale.

    • To scale up classic storage, you need to add at least 1 GB each time. The value must be an integer.
    • To scale up cloud native storage, you need to add at least 10 GB each time. The value must be an integer multiple of 10.

  4. On the displayed page, confirm the storage space.

    • Yearly/Monthly
      • If you need to modify your settings, click Previous.

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

  5. Check the results.

    • During the scaling process, the instance status becomes Scaling up.
