I am looking for some help setting up an NFS shared drive on my RT-AC68U router running the current Asuswrt-Merlin release.
I have used the webgui on the router to setup the usb drive as rw. The share will only be available on my LAN to 3 other Linux machines.
To me it looks like the share is running OK on the router. On the router I see the following:

on the ubuntu client, I see:

I look on the mounted drive for a file:
ls /mnt/nfsmount testfile*
ls: cannot access 'testfile*': No such file or directory
nothing there, so I create a file:
john@Mintbox:~$ touch /mnt/nfsmount/testfile1
john@Mintbox:~$ ls /mnt/nfsmount testfile*
ls: cannot access 'testfile*': No such file or directory
look a second time and it appears:
john@Mintbox:~$ ls -alg /mnt/nfsmount
-rwxrwxrwx 1 root 0 Nov 7 10:51 testfile1
This happens for all files using cp or mv to place files on the mounted drive. Everytime there is an initial failed attempt followed by a success.
I am at a loss as to how to fix, so any advice is greatly appreciated. I am pretty my a noob with NFS.
