Scaling Up Storage Space

Scenarios

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

  • You cannot scale up a DB instance in Creating, Changing instance class, Adding node, or Deleting node status.
  • Storage space can only be scaled up. It cannot be scaled down.
  • If you scale up a DB instance with disks encrypted, the expanded storage space will be encrypted using the original encryption key.
  • You cannot scale up the storage space of a config for the cluster instances.
  • During the scale-up process, the DB instance will not restart, and your services will not be interrupted.

Cluster

  1. Log in to the DDS console.
  2. On the Instance Management page, click the target cluster instance.
  3. In the Node Information area on the Basic Information page, click the shard tab, locate the target shard, and click Scale Storage Space in the Operation column.
  4. On the displayed page, specify the desired storage space, and click Submit.

    You must add a minimum of 10 GB each time you scale up, and only multiples of 10 GB are allowed. The maximum amount of storage space is 2000 GB.

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

    • Yearly/Monthly
      • If you need to modify your settings, click Previous to go back to the page for you to specify details.
      • If you do not need to modify your settings, click Submit to go to the payment page and complete the payment.
    • Pay-per-use
      • If you need to modify your settings, click Previous to go back to the page for you to specify details.
      • If you do not need to modify the specifications, click Submit to scale up the storage space.

  6. Check the scale-up result.

    • This process takes about 3 to 5 minutes. The status of the DB instance in the instance list is Scaling up.
    • In the upper right corner of the DB instance list, click to refresh the list. The instance status changes to Available.
    • In the Node Information area on the Basic Information page, click the shard tab and check whether the scale up was successful.

Replica Set

  1. Log in to the DDS console.
  2. On the Instance Management page, locate the target replica set instance and click Scale Storage Space in the Operation column.
  3. On the displayed page, specify the desired storage space, and click Next.

    You must add a minimum of 10 GB each time you scale up, and only multiples of 10 GB are allowed. The maximum amount of storage space is 3000 GB.

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

    • Yearly/Monthly
      • If you need to modify your settings, click Previous to go back to the page for you to specify details.
      • If you do not need to modify your settings, click Submit to go to the payment page and complete the payment.

      • If you do not need to modify the specifications, click Submit to scale up the storage space.

  5. Check the scale-up result.

    • This process takes about 3 to 5 minutes. The status of the DB instance in the instance list is Scaling up.
    • In the upper right corner of the DB instance list, click to refresh the list. The instance status changes to Available.
    • In the Storage Space area on the Basic Information page, check whether the scaling up is successful.

Single Node

  1. Log in to the DDS console.
  2. On the Instance Management page, locate the target single node instance and click Scale Storage Space in the Operation column.
  3. On the displayed page, specify the desired storage space and click Next.

    You must add a minimum of 10 GB each time you scale up, and only multiples of 10 GB are allowed. The maximum amount of storage space is 1000 GB.

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

    • Yearly/Monthly
      • If you need to modify your settings, click Previous to go back to the page for you to specify details.

      • If you do not need to modify the specifications, click Submit to scale up the storage space.

  5. Check the scale-up result.

    • This process takes about 3 to 5 minutes. The status of the DB instance in the instance list is Scaling up.
    • In the upper right corner of the DB instance list, click to refresh the list. The instance status changes to Available.
