Mount a Share from another NAS to PR4100

Need some hand holding help please - New to using linux

Trying to setup plex - have 2 NAS with data
Trying to map a NFS share from my ix4 nas to my new PR1400
I have posted what information I know to give, so if there is other information that is needed, please let me know, and maybe how to get it.

Lenovo ix4-300d
IP address
With a NFS share
Location: /nfs/TVShows
NFSv4 Location: /TVShows
Permissions Everyone read / write

Second NAS Pr4100
Share Profile
Share Name

Share Description Test
Public ON
Recycle Bin OFF
Media Serving OFF
Oplocks ON
Usage 4.0K

Share Access
FTP Access OFF
WebDAV Access ON
NFS AccessON Configure >>
Mount Point: nfs://

Host *
Write ON

Run this command busybox mount -o nolock,ro,hard,intr,vers=3 -t nfs /mnt/HD/HD_a2/test

mount: failed, reason given by server: Permission denied
mount: mounting on /mnt/HD/HD_a2/test failed: Bad file descriptor

Now I am trying to verify if my mount point on my PR4100 is active, but when I try showmount

-sh: showmount: not found

Any ideas - what am I missing



I have never tried this but I am sure we have a lot of experienced users on this community that might be able to share some experience with us on this thread.
