NFS mounting issues

[Viktor Jaep]

I also tried Victa Jaep new backupmon.sh that implemented those changes

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/BACKUPMON/develop/backupmon.sh" -o "/jffs/scripts/backupmon.sh" && chmod 755 "/jffs/scripts/backupmon.sh"

Still error bad file descriptor.
Reverted back to unchanged backupmon.sh

Can you try this:

mkdir -m 755 -p "/var/lib/nfs"
modprobe nfs nfsv3
portmap

...then try your mount statement

Still the same, bad file descriptor.

server /etc/exports
I've tried
/srv/nfsshared 192.168.50.0/24(rw,root_squash,anonuid=1000,anongid=1000)
/srv/nfsshared 192.168.50.0/24(rw,no_root_squash,anonuid=1000,anongid=1000)
/srv/nfsshared 192.168.50.0/24(rw,root_squash)

What are the permissions on your server? Try setting 777 as a tes (allow everything for everyone).

Also make sure your NAS allows nvfv3 connections.

I just remembered.... I believe I read in the changelog for 1006 firmware that NFS is broken. I am away from home now for a few days, I will check later. I am running 388 codebase on my ax86u pro.

Changed permissions to 777 on server /srv/sfsshared, nfsv3 is enabled by default on server. no change.

The 3006.102.x Asus-Merlin Change Log only mentions NFS not supported on WiFi 7 devices.

3006.102.1 (28-Jun-2024)
...
- NOTE: Wifi 7 devices don't support NFS (issue with new
toolchain), QoS classification page (issue with
TrendMicro BWDPI) or Wifi Radar (not updated by
Broadcom).

Ok. Thanks @bennor I knew I read something about NFS not working on something. You saved me looking it up.

@pedeb04 , I am afraid that I am out of ideas. Bad file descriptor is usually a sign that a permission issue exists. Mind me asking what you are using as a NAS?

Using the modified steps from above, I am able to mount an NFS share that I have set up as a test on a Ubuntu 22.04 bare metal machine. I'll send you my export contents later today when home. I do use a couple other options, but I doubt they would make a difference.

I am using Ubuntu server 24.04 and my Desktop is Ubuntu 24.04
When I mount the nfs share on the server from the desktop I notice the nfsvers=4.2

peter@nuc:~$ nfsstat -m
/mnt/nfs from 192.168.50.46:/srv/nfsshared
 Flags:    rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.50.175,local_lock=none,addr=192.168.50.46

If I try to mount using nfsvers=3 from the desktop but it times out.
I've tried to find a way to change/configure the server nfs export share to nfs3 with no luck so far. I'm thinking this is where the issue is.
