ResizeDisk-阿里云帮助中心

Resizes a system disk or a data disk.

Operation description

Note

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：
- 云盘状态为使用中（In Use）或者待挂载（Available）。
- （强烈建议）已为云盘创建快照，做好数据备份。具体操作，请参见创建快照。
- 如果您是全新购买的数据盘，请先完成初始化再执行扩容操作。更多信息，请参见初始化概述。

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
DiskId	string	Yes	The ID of the disk. You can call the DescribeDisks operation to query available disk IDs.	d-bp67acfmxazb4p****
Type	string	No	The method that you want to use to resize the disk. Valid values: offline (default): resizes the disk offline. After resizing a disk offline, you must restart the instance in the console or call an API operation RebootInstance make the operation take effect. online: resizes the disk online without the need to restart the instance. You can resize ultra disks, standard SSDs, ESSDs, and elastic ephemeral disks online.	offline
