You can call this operation to resize a system disk or data disk.

Description

Note Before you call this operation, you must check the partition format of the disk. You cannot resize an MBR-formatted disk to greater than or equal to 2 TiB without data loss. To resize an MBR-formatted disk to greater than or equal to 2 TiB in size, we recommend that you create and attach a new data disk with the desired size. Then, you can partition and format the new data disk to GPT and copy data from the MBR-formatted data disk to the new GPT-formatted data disk. For more information, see Resize cloud disks offline.
  • You can resize the following categories of disks: basic disks (cloud), ultra disks (cloud_efficiency), standard SSDs (cloud_ssd), and enhanced SSDs (ESSDs) (cloud_essd).
  • You cannot resize a disk when a snapshot is being created for the disk.
  • The instance to which the disk to be resized is attached must be in the Running (Running) or Stopped (Stopped) state.
  • After you resize a disk, its partitions and file systems are not changed. You must manually allocate the storage space on the disk after it is resized.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes ResizeDisk

The operation that you want to perform. Set the value to ResizeDisk.
DiskId String Yes d-bp67acfmxazb4p****

The ID of the disk.

NewSize Integer Yes 1900

The new disk capacity. Unit: GiB. Valid values:

  • Ultra disk (cloud_efficiency): 20 to 32768
  • Standard SSD (cloud_ssd): 20 to 32768
  • Enhanced SSD (cloud_essd): 20 to 32768
  • Basic disk (cloud): 5 to 2000

The new disk capacity must be greater than the original disk capacity.

Type String No offline

The method that you use to resize the disk. Default value: offline. Valid values:

  • offline. After you resize a disk offline, you must restart the instance by using the ECS console or by calling the RebootInstance operation for the resizing operation to take effect. For more information, see Restart the instance and RebootInstance.
  • online. After you resize a disk online, the resizing operation takes effect immediately and you do not need to restart the instance. You can resize ultra disks, standard SSDs, and ESSDs online.
ClientToken String No 123e4567-e89b-12d3-a456-426655440000

The client token that is used to ensure the idempotence of the request You can use the client to generate the value, but you must make sure that it is unique among different requests. The ClientToken value must contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.

Error codes

HTTP status code Error code Error message Description
403 InvalidDataDiskSize.ValueNotSupported The specified DataDisk.n.Size beyond the permitted range, or the capacity of snapshot exceeds the size limit of the specified disk category. The error message returned because the specified DataDisk.N.Size parameter is invalid or the snapshot size exceeds the maximum capacity that is allowed for the specified category.
404 InvalidDiskId.NotFound The specified disk does not exist. The error message returned because the specified disk does not exist. Check whether the disk ID is correct.
404 InvalidInstanceId.NotFound The specified InstanceId does not exist. The error message returned because the specified Instance does not exist. Check whether the instance ID is correct.
403 OperationDenied The type of the disk does not support the operation. The error message returned because the specified disk category does not support this operation.
403 OperationDenied The status of the disk or the instance that the disk is attaching with does not support the operation. The error message returned because the operation is not supported while the disk or instance is in the current state.
403 InvalidDiskSize.TooSmall Specified new disk size is less than the original disk size. The error message returned because the specified new disk capacity is smaller than the original disk capacity.
403 InvalidDiskSize.TooLarge Specified new disk size is beyond the permitted range. The error message returned because the specified new disk capacity exceeds the capacity limit.
403 InstanceExpiredOrInArrears The specified operation is denied as your prepay instance is expired (prepay mode) or in arrears (afterpay mode). The error message returned because the subscription instance has expired. Renew the instance first.
403 DiskError IncorrectDiskStatus The error message returned because the status of the specified disk is invalid.
