We have a Terastation TS-RVHL(NAS) and we cannot get it to add storage successfully. We have updated to the latest firmware v1.14 and at a hault. I'll copy and paste the error we get:
Call "HostDatastoreSystem.CreateNasDatastore" for object "datastoreSystem-49" on vCenter Server "VCENTER.GCFA.ORG" failed. NFS mount 10.23.80.98:/mnt/array1/ISO failed: The mount request was denied by the NFS server. Check that the export exists and that the client is permitted to mount it.
