[EN] NFS mount fails on boot

[eriefisher]

I have two laptops. I have a data partition shared via NFS from laptop 1 to laptop 2 without issue. It works as expected. I am now trying to share a data partition on laptop 2 to laptop 1 but it won't mount on boot. I've compared the set up on both laptops and they are identical except for the specific paths. Once in a desktop I open a terminal and:

Code: [Select]

mount -abut it fails with:

Code: [Select]

 mount.nfs: failed to prepare mount: Operation not permitted

mount: (hint) your fstab has been modified, but systemd still uses
      the old version; use 'systemctl daemon-reload' to reload.
This shouldn't be the case because it has been done several times as well as several reboots but I keep getting the same response. Anyway, again I:

Code: [Select]

systemctl daemon-reloadThe daemon appears to reload without argument and I can mount the share manually with:

Code: [Select]

mount -aThe share mounts successfully and I can access it read/write no problem until I reboot and need to start over again. Hopefully someone can give me a clue as to what's going on here. I have attached /etc/exports from the server laptop with the share and the /etc/fstab from the client laptop.

cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported

# Example for NFSv2 and NFSv3:
