Did you ever get a response on this? I noticed the help section for exclusive shares in unraid 7.2.3 no longer lists NFS exports as a limitation. Does this help? See below If set to Yes, share directories under /mnt/user are actually symlinks to the share directory on a storage volume provided the following conditions are met: The Primary storage for a share is set to a pool. The Secondary storage for a share is set to none. The share exists on a single volume. The advantage of exclusive shares is that transfers bypass the FUSE layer which may significantly increase I/O performance.
