Trying to set up a shared folder between an embeded linux device and my development box. Short version is that the client side folder remains empty even when I create a file on the client side. Below is setup and some testing. I have included some output that I have seen asked for in other similar questsion, (none of which helped me ovbiously) but if there is something else that would be helpful, let me know.

Server Side setup:

 $/mnt/nvme0n1p2$ uname -r
 4.13.0-45-generic

/etc/exports has this line at the end. Have tried with/without no_root_squash,crossmnt,nohide

/mnt/nvme0n1p2/ <CLIENT_IP>(rw,sync,no_subtree_check,no_root_squash,crossmnt,nohide)

Shared Folder (permissions were lower, but wanted to rule that out as a problem)

$/mnt$ ls -la
total 16K
drwxr-xr-x 4 root root 4.0K Oct 17 15:01 .
drwxr-xr-x 28 root root 4.0K Jun 26 11:05 ..
drwxrwxrwx 2 root root 4.0K Oct 23 16:39 nvme0n1p2
$cd nvm20n1p2/
$/mnt/nvme0n1p2$ ls
total 4.0K
-rwxrwxrwx 1 root root 6 Oct 23 15:52 testfile

restart server

/etc/init.d/nfs-kernel-server restart

Client Side setup:

$ uname -r
2.4.26-ts11

$ cd /mnt/host/
$ ls -la
drwxr-xr-x 1 root root 2048 Jan 1 00:41 .
drwxr-xr-x 1 root root 2048 Jan 1 1970 ..

$ mount
...others
$ mount -t nfs <SERVER_IP>:/mnt/nvme0n1p2 /mnt/host
$ mount
...others
<SERVER_IP>:/mnt/nvme0n1p2 on /mnt/host type nfs (rw,v3,rsize=32768,wsize=32768,hard,udp,lock,addr=10.0.209.101)

$ cd /mnt/host/
$ ls -la
...Nothing 


$ echo "hello" > testfile2
$ ls
...still nothing

But back on the server

$/mnt/nvme0n1p2$ ls
total 8.0K
-rwxrwxrwx 1 root root 6 Oct 23 15:52 testfile
-rw-r--r-- 1 root root 6 Oct 23 16:39 testfile2
$/mnt/nvme0n1p2$ cat testfile2
hello
