查询磁盘扩容范围
功能介绍
此接口可用于查看磁盘扩容操作时支持的扩容范围。
约束限制:
磁盘扩容功能仅8.1.1.203及以上版本支持,并且创建集群规格需要为云数仓SSD云盘或实时数仓类型。
按需+折扣套餐包消费模式下,存储扩容后超出折扣套餐包部分将按需收费。
调用方法
请参见如何调用API。
URI
GET /v1/{project_id}/clusters/{cluster_id}/storage-expand-range
请求参数
无
响应参数
状态码:200
参数 |
参数类型 |
描述 |
---|---|---|
min_size |
Integer |
参数解释: 扩容后单节点磁盘最小值(单位GB)。 取值范围: 不涉及。 |
max_size |
Integer |
参数解释: 扩容后单节点磁盘最大值(单位GB)。 取值范围: 不涉及。 |
current_size |
Integer |
参数解释: 磁盘当前值(单位GB)。 取值范围: 不涉及。 |
step |
Integer |
参数解释: 磁盘步长大小(单位GB)。比如当前单节点磁盘20GB,步长为20,则扩容后单节点磁盘大小至少为40GB。 取值范围: 大于等于10。 |
