Querying the Disk Capacity Expansion Range

Function

This API is used to query capacity range that a disk can be expanded to.

Constraints

Disk capacity expansion can be performed only for cloud data warehouses using SSD or hybrid data warehouses. Only version 8.1.1.203 and later are supported.

In the pay-per-use + discount package mode, after the disk capacity is expanded, the capacity exceeding the package will be billed on a pay-per-use basis.

Calling Method

For details, see Calling APIs.

URI

GET /v1/{project_id}/clusters/{cluster_id}/storage-expand-range

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Project ID. To obtain the value, see Obtaining a Project ID. Constraints N/A Range N/A Default Value N/A
cluster_id	Yes	String	Definition Cluster ID. For details about how to obtain the value, see Obtaining the Cluster ID. Constraints N/A Range N/A Default Value N/A

Request Parameters

None

Response Parameters

Status code: 200

**Table 2** Response body parameters
Parameter	Type	Description
min_size	Integer	Definition Minimum disk capacity of a single node after the expansion, in GB. Range N/A
max_size	Integer	Definition Maximum disk capacity of a single node after the expansion, in GB. Range N/A
current_size	Integer	Definition Current disk capacity, in GB. Range N/A
step	Integer	Definition How much the disk capacity is expanded at a time, in GB. For example, if the disk capacity of a single node is 20 GB and this parameter is set to 20, the disk capacity after the expansion is at least 40 GB. Range Greater than or equal to 10
