<p>
The size, in GB, of the ML storage volume to attach to the notebook instance. The default value is 5 GB. ML
storage volumes are encrypted, so SageMaker can't determine the amount of available free space on the volume.
Because of this, you can increase the volume size when you update a notebook instance, but you can't decrease the
volume size. If you want to decrease the size of the ML storage volume in use, create a new notebook instance
with the desired size.
