VSC Provisioning does not support provisioning a datastore in a qtree, nor does it support mounting a datastore that is in a qtree.
However, VSC does recognize that customers have a history of using qtrees for datastores, and so does support them as follows:
* You can clone (or redeploy) into an existing datastore that is backed by a qtree
* You can run space reclamation for a datastore that is backed by a qtree (but not a qtree within a vfiler)
