指定节点类型规格变更
功能介绍
当集群的数据面业务变化,需要动态调整集群的节点规格和节点存储类型时可以调用此接口进行变更操作。
- 支持变更节点规格的集群类型:Elasticsearch、OpenSearch和Logstash。
- 支持变更节点存储类型(磁盘类型)的集群类型:Elasticsearch和OpenSearch。在变更节点存储类型(磁盘类型)前,建议备份所有关键数据,以免造成数据丢失。
调用接口时可以指定以下节点类型:
约束限制
- 确认需要更改的集群处于“可用”状态,且无正在进行的任务。
- 使用本地盘的节点不支持变更节点规格和节点存储类型。
- 不支持同时变更节点规格和节点存储类型。
- 仅数据节点和冷数据节点支持变更节点存储类型。
- 变更节点存储类型的过程涉及数据迁移,单个节点的数据迁移的超时阈值为48小时,超时将导致变更失败。当集群数据量大时,建议手动调整数据迁移速率,避免在业务高峰期操作。
- 无Master节点的集群:当数据节点数和冷数据节点数之和大于或等于3时(即“ 数据节点数 + 冷数据节点数 ≥ 3”)才支持变更节点存储类型。
- 有Master节点的集群:当数据节点数大于或等于2时(即“ 数据节点数 ≥ 2”)才支持变更节点存储类型。
- 变更节点存储类型时,会有一个节点无法提供服务,为保证业务连续性,请确认每个AZ中同类型节点数大于或等于2,数据节点数和冷数据节点数之和大于索引副本数的最大值加1,即“数据节点数 + 冷数据节点数 > 索引副本数的最大值+1”。
- 变更节点规格会直接下线节点,为保证业务连续性请确保所有索引都有副本。
- 请确认下线一个节点之后的磁盘使用率小于80%。

请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
operation_type |
否 |
String |
参数解释: 集群节点的变更类型。 约束限制: 不涉及 取值范围: 默认取值: vm |
new_flavor_id |
是 |
String |
参数解释: 变更后的节点规格ID或者节点存储类型(磁盘类型),由参数operation_type决定。 约束限制: 取值范围和参数operation_type相关联。 取值范围: 1、当参数operation_type为vm时,new_flavor_id是节点规格ID。 该参数通过获取实例规格列表接口获取,根据name属性所需要的规格,选择对应的flavor_id。 2、operation_type为volume时,new_flavor_id为节点存储类型(磁盘类型),支持如下类型: 默认取值: 不涉及 |
need_check_replica |
否 |
Boolean |
参数解释: 变更前是否进行索引副本校验。 约束限制: 不涉及 取值范围: 默认取值: true |
is_auto_pay |
否 |
Integer |
参数解释: 是否自动支付。下单订购后,是否自动从客户的华为云账户中支付,而不需要客户手动去进行支付。 约束限制: 该参数适用于包周期集群。 取值范围:
默认取值: 0 |
need_check_cluster_status |
否 |
Boolean |
参数解释: 变更前是否检测集群状态。 约束限制: 不涉及 取值范围: 默认取值: true |
cluster_load_check |
否 |
Boolean |
参数解释: 变更前是否检测集群负载。集群负载检测项包含:
约束限制: 不涉及 取值范围: 默认取值: true |
