• To connect to the NBD server you will first need an NBD client and driver on your PC.
• The Ceph MSI installer bundles a signed version of the WNBD driver.
  It can be downloaded from here: https://cloudbase.it/ceph-for-windows/
• Install the client and reboot.
• Open CMD as administrator and run:

  wnbd-client.exe unmap hdd1
