Sharing NFS with another linux computer

Before configuring the truenas console, create the directory and change the owner to nobody:nobody. (To prevent privilege elevation risks, it's safest for NFS to treat the NFS connection user as "nobody."

sudo mkdir /mnt/nas/Share/nfs
sudo chown -R nobody:nobody /mnt/nas/Share/nfs

Follow the instructions at (I could reproduce them here, but Truenas's will always be more up to date than what I can do - all I can do is add advice around it!)

NOTE: On the client you may need to install nfs-common and then you just mount it!

sudo apt install nfs-common
sudo mount /mnt/
