Resizes disk with IaaS-native methods. Assume that disk was detached from all VMs. Set property director.enable_cpi_resize_disk to true to have the Director call this method.

Depending on the capabilities of the underlying infrastructure, this method may raise an Bosh::Clouds::NotSupported error when the new_size is smaller than the current disk size. The same error is raised when the method is not implemented.

If Bosh::Clouds::NotSupported is raised, the Director falls back to creating a new disk and copying data.


  • disk_cid [String]: Cloud ID of the disk to resize; returned from create_disk.
  • new_size [Integer]: New disk size in MiB.


No return value
