扩容一块磁盘，支持扩容系统盘和数据盘。
接口说明
扩容前，请务必查询云盘采用的分区格式。如果是 MBR 格式，不支持扩容到 2TiB 以上，否则会造成数据丢失。对于 MBR 分区扩容，建议您重新创建并挂载一块数据盘，采用 GPT 分区格式后，再将已有数据拷贝至新的数据盘上。更多详情，请参见扩容云盘容量。
-
支持扩容的磁盘类型包括普通云盘（
cloud）、高效云盘（cloud_efficiency）、SSD 云盘（cloud_ssd）、ESSD 云盘（cloud_essd）、ESSD Entry 云盘（cloud_essd_entry）、ESSD AutoPL 云盘（cloud_auto）、弹性临时盘-标准版（elastic_ephemeral_disk_standard）和弹性临时盘-高级版（elastic_ephemeral_disk_premium）、 ESSD 同城冗余云盘（cloud_regional_disk_auto）。 -
正在创建快照的云盘不支持扩容。请您等待快照创建完成后，再开始执行扩容操作。
-
该接口不能扩容分区和文件系统，您需要在扩容云盘容量后自行分配分区和文件系统，具体操作，请参见扩容分区与文件系统（Linux）和扩容分区与文件系统（windows）。
-
开启多重挂载特性的云盘支持在线扩容和离线扩容，请确保磁盘挂载的实例满足以下条件：
在线扩容时，实例状态为运行中（
Running）。离线扩容时，实例状态为运行中（
Running）或已停止（Stopped）。
-
请确保云盘满足以下条件：
