Scaling Disk Space

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

Usage Notes

  • Storage space of an instance can be scaled up or down.
  • To scale down storage, ensure the new storage space is at least 1.25 times more than the used space and rounded up.
  • Scaling up storage does not interrupt your services. After storage scale-up is complete, you do not need to restart your instance.
  • Scaling down storage does not interrupt your services. After storage scale-down is complete, you do not need to restart your instance.
  • If your instance is a yearly/monthly instance and its storage is used up, you will be billed on a pay-per-use basis for any additional storage. Scale up your storage space, and you can pay for the additional storage at yearly/monthly rates.
  • The storage details can be displayed on the Instances page. To query the details, choose Service Tickets > Create Service Ticket in the upper right corner of the console and contact customer service.

Procedure

  1. Log in to the Huawei Cloud console.
  2. In the service list, choose Databases > GeminiDB Cassandra API.
  3. 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.

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

    You must select at least 1 GB each time you scale, and only an integer is allowed.

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

    • For yearly/monthly instances
      • If you need to modify your settings, click Previous.
      • If you do not need to modify your settings, click Next 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.

  6. Check the scaling result.

    • During the scaling process, the instance status becomes Scaling storage space.
    • After the scaling process, the instance status becomes Available.
    • Click the instance name. In the Storage Space area on the Basic Information page, check the new storage space.
