8.10. Deleting Orphan Disks

For the Oracle VM VirtualBox and Microsoft Hyper-V desktop providers, storage is provided by external storage volumes, and this storage is assigned to desktops and templates as you create them. Eventually, you may delete the desktops and templates, but the associated storage is not automatically released.

Orphan disks are those storage volumes that are not currently mapped to any desktop or template and can be deleted to free up space. Orphan disks that have descending clones cannot be deleted.

Note

Some orphan disks may still hold important data. Make sure the data on an orphan disk is no longer needed before you delete it.
