ResizeDisk

Description

When you call this interface, consider the following:

• You can only extend the size of a data disk instead of a system disk.

• You can only extend the size of a basic cloud disk (Cloud), an ultra cloud disk (Cloud_efficiency), or an SSD cloud disk (Cloud_ssd).

• You cannot extend the size of a disk when it is used to create a snapshot.

• If a data disk has been attached to an ECS instance:

  • The instance must be in the Running (Running) or Stopped (Stopped) status.

  • The instance must be restarted  in the ECS console or by calling the API RebootInstance after the size extension.

• This action only extends the capacity of a data disk, and the partitions and the file system are not modified. After the operation, you must manually allocate the storage space.
