First, we need to try to simulate if we can add an extra disk using Longhorn volume or not.

First, we need to try to simulate if we can add an extra disk using Longhorn volume or not.

By creating a loopdeivce and mount it to a directory, we can observe it from Harvester UI, but it seems not regard as a block device by Harvester.
Just open an enhancement ticket harvester/harvester#6093 (comment) for further input and discussion.
