Manually Scaling Up Storage Space

Scenarios

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

Usage Notes

  • To keep services accessible, scale up storage space when the storage usage exceeds 80%.
  • 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 Redis 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.

  • Table 1 describes the read-only status of instances with classic storage.
    Table 1 Read-only status of instances with classic storage

    Storage

    Description

    < 600 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.

    ≥ 600 GB
    • If the remaining storage is less than 18 GB, the instance becomes read-only.
    • When the remaining storage is greater than or equal to 90 GB, the instance exits the read-only mode.
  • Table 2 describes the read-only status of instances with cloud native storage.

    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.

Procedure

  1. Log in to the GeminiDB console.
  2. On the Instances page, click the target instance.
  3. In the Specification Information area on the Basic Information page, click Scale for an instance.

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

    • 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.

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

    • Yearly/Monthly
      • If you need to modify your settings, click Previous.
      • If you do not need to modify your settings, click Submit and complete the payment.
    • Pay-per-use
      • If you need to modify your settings, click Previous.
      • If you do not need to modify your settings, click Submit.

  6. Check the results.

    • When the scaling task is ongoing, the instance status is Scaling storage space.
    • After the scaling task is complete, the instance status becomes Available.
    • Click the instance name. In the Specification Information area on the Basic Information page, you can view the new storage space.

  1. Log in to the GeminiDB console.
  2. On the Instances page, locate the instance whose storage space you want to scale and choose More > Scale Storage Space in the Operation column.
