Scaling Up Storage Space

Scenarios

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

  • You can scale up a DB instance a maximum of four times.
  • You cannot scale up a DB instance in Abnormal status.
  • You cannot scale up a DB instance in Creating, Changing instance class, Adding node, or Deleting node status.
  • You cannot scale down storage space.
  • 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.

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 1,000 GB.

  5. Check the scaling-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 scaling up is 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 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 2,000 GB.

  4. Check the scaling-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.
