RPi 4B - Network File Share - nfs

Trying to get nfs between workstation and mill.
Posted here hoping the RPi developers may have a solution.

nfs server - workstation: hp desktop ubuntu 24.04.
nfs client - mill: RPi 4B 4GB LC 2.9.4.
 
wifi is working fine.
sftp between the stations without issue.

nfs works after a manual mount on the client.
Cannot get nfs to mount automatically at start up.

The /etc/fstab file is populated (to the best of my searching).
Tried a couple of web suggestions, but no solution yet.

Looked through the startup log:
    - "mount.nfs: Network is unreachable".

Tried several web suggestions, including increasing the wait time.

Did some searching on the Raspberry Forum without success.

When I issue a terminal command "mount' after starting LC, there is a response about an old version and to use "systemctl-daemon reload".
After reboot, entered 'systemctl-daemon reload', got 'command not found'.
Tried 'systemctl daemon-reload', accepted without success.

Any suggestions getting the mount at start-up ?

My guess is that it's trying to mount the nfs share before the wifi interface is up.
So you may have to look through dmesg to see when the nfs share is being mounted and when the wifi interface is being brought up.
Do you have any issues trying to mount the share after the wifi network is up ?

There may be a way to do it via systemd that waits for the wifi network to come up, I've got a couple of ones that turn off the power related stuff for wifi, but only after the interface is up. Might be able to use the same mechanism to mount the shares once that interface is up.

I'd suggest this isn't a issue related to the Raspberry Pi platform but any situation where an nfs or samba share is automounted and the required interface isn't up at that time.

"automount nfs but wait for interface to be up" is a google search phrase that brings up some good answers. Apparently there are some options you can add to fstab to help out.

Thanks for the response.

Changed the parameters in the /etc/fstab entry to:
defaults,x-systemd.automount,x-systemd.mount-timeout=30,_netdev,x-systemd.after=network-online.target 0 0

This works fine, thanks.

My config, original non-auto line commented out new auto one below
#192.168.1.70:/exports/share /nfs/share nfs users,noauto,hard,intr 0 0
192.168.1.70:/exports/share /nfs/share nfs users,_netdev,auto,x-systemd.automount,x-systemd.requires=network-online.target,x-systemd.device-timeout=5s 0 0

Thanks mate, must have been posting at the same time.
Anyways I've added this thread to the RPi Index thread under Linuxcnc General Questions.
