Tvheadend recording to a network drive

To share with nfs, you need to create /etc/exports on the Pi4 containing just this line:

/media/Passport2 192.168.1.0/24(rw,sync,no_root_squash,no_subtree_check)

Then on the Pi3 either sudo mkdir /mnt/Recordings and use fstab. I don’t think username and password are necessary. Or don’t create that directory and use autofs where /etc/auto.nfs.shares looks like

/mnt/Recordings -fstype=nfs4 192.168.1.140:/media/Passport2/Recordings

Edit /etc/auto.master as described in the linked post above.
After setting it up systemctl restart nfs-server on Pi4 and systemctl restart autofs on Pi3.
