I have an EX 4100 that I use for Plex. Just got a new PR4100 that I want use as the main server and join with my existing EX. Is there a way to do that?
There is a way to do this, but it requires SSH and some startup scripts if you want to survive reboots.
Mount the EX as an NFS/smb share on the PR4100, e.g. to /mnt/exbox … then add a Plex entry to this location.
Hi,
Any chance you can do a step by step guide for this? I’d love to have my pr4100 as my plex server and my ex4100 run connected up to it.
Let’s assume you have a ‘movie’ share on the EX4100 with IP address 192.168.0.100 and you want to NFS mount it on the PR4100.
In the EX4100 web UI, in the shares tab, enable NFS for the movie share. Eventually configure it to be writeable if you need it… but best to leave it off when you don’t need it.
Then ssh into the PR4100.
Create a mount point for the movie share, e.g. ex_movie
mkdir -p /mnt/ex_movie
Now mount the movie share on this mount point. Any NFS exported shares are available at /nfs.
mount 192.168.0.100:/nfs/movie /mnt/ex_movie
You should have access now to your EX4100 on your PR4100. Let’s see:
ls -l /mnt/ex_movie
In Plex, add a library with this mount point.
Make sure you unmount the directory when you want to reboot either of the NAS to prevent lockups.
umount /mnt/ex_movie
If you want this to happen automatically on boot / shutdown, you could put the mount / umount commands in the start.sh / stop.sh of one the apps in /shares/Volume_1/Nas_Prog … that let’s you toggle the mount from the web UI by enabling the app. Note that Plex updates often so I wouldn’t put it there as your changes are lost on app update.
Disclaimer: do at own risk etc…
Hi Mate, i have the same configuration as you, un PR and an OLD EX4100 Raid5 (4x6TB) almost full of multimedia files.
I’m already using NFS shared folder on my 2 RaskperryPi (2 and 3B+) and the shares work great on this 2 Linux Distributions
Using your commands, once i try to mount the shared folder on my PR4100 i receive this error message.
Note that i’m using the same address used on the other 2 devices (RPi)
After i created the folder on /mnt as you suggested
root@MyCloudPR4100 root # mount 192.168.1.106:/nfs/Public /mnt/ex_movies
mount: wrong fs type, bad option, bad superblock on 192.168.1.106:/nfs/Public,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
Actually below commands i’m using to Mount the NFS folder on RaspberryPi and it works great.
Raspberry 2
mount -t cifs -o user=XXXX,passwd=XXXXXX,rw,file_mode=0777,dir_mode=0777 //192.168.1.106/Public //home/pi/wdpublic
Raspberry 3
mount -t cifs -o username=XXXX,password=XXXXXX,uid=$(id -u),forceuid, //192.168.1.106/Public /home/pi/wdpublic
Any Idea?
Thanks
CIFS (samba) and NFS are not the same… your rpis are using CIFS, while my commands were for NFS.
On your raspberry pi, what is the output of
showmount -e 192.168.1.106
On your PR4100, maybe try this
mkdir /mnt/ex2pub
mount -t cifs -o user=XXXX,passwd=XXXXXX //192.168.1.106/Public /mnt/ex2pub
Hi, sorry you are right… I used NFS to connect the volume via MAC. I get confused 
this is the output for showmount actually
pi@raspberrypi:~ $ showmount -e 192.168.1.106
Export list for 192.168.1.106:
/mnt/HD/HD_a2/Public *
/mnt/HD/HD_a2/Francy *
/mnt/HD/HD_a2/erosoft *
/mnt/HD/HD_a2/pi *
I’m trying your suggested command… i will revert back asap… Thanks
just tried now.
Same error message
root@MyCloudPR4100 root # mount -t cifs -o user=XXXX,passwd=XXXXXX //192.168.1.106/Public /mnt/ex2pub
mount: wrong fs type, bad option, bad superblock on //192.168.1.106/Public,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
To add more info, i can confirm that NFS is active and configured, since it is used via MAC OSX
Okay… let’s try NFS then.
On the PR4100, do
mount -t nfs 192.168.1.106:/nfs/Public /mnt/ex2pub
The /nfs dir is a symlink to /mnt/HD/HD_a2, so both should work.
And include dmesg | tail output please.
Also check the EX2 web interface and ensure NFS export is configured for the share (in the shares tab).
Thanks, sorry i haven’t read your reply…
let me try.
Thanks
These are my try out… and the Output requested.

Just to add more info, that might be useful, these are the commands i use on the Apple Script to Mount all the NFS volume
What about this command?
