The haneWin NFS server does not have quotas per exported NFS share and cannot specify shares size. The size of my share was small (55GBytes on an old USB drive) and it was correctly identified from both the camera and the NVR firmware. The camera formatted the share successfully as SMB, the NVR failed to format it through the NFS protocol.
Another question is: Does the NVR support SMB?
