Ubuntu Server with Synology Storage - NFS share not browsable

Plex Media Server
1

I haven’t had my Plex set up since I moved about 3 years ago… So when re-building it I thought I’d utilize my Synology for storage but have the server live on a Ubuntu Linux box to get some extra processing power behind the transcoding…

The issue I’m having is that I can’t browse the NFS path on the Synology from the Ubuntu server.
From the server, “ls -l /mount/plex” returns “total 0”

…but here’s where it gets interesting… If I mount the NFS share to my Chromebook using the same credentials, I can browse it with no issues. This makes me think that the settings on the Synology are correct (but I could be wrong)

I’m currently using the following to mount the volume from the Ubuntu server:
172.16.18.74:/volume1/shared_data /media/plex nfs intr,rw,vers=4,auto,async,bg 0 0

And the Synology has the following:
read/write
squash: all users to admin
security: sys
Enable Asynchronous
Allow users to access mounted subfolders

My Linux skills are sub-par at best, so I may just be missing something stupid… I’m sure more info or logs are necessary - just let me know what I’m missing and I’ll update. Any help is appreciated…

Don’t put the mount point in /media.
Nautilus claims that. (Automounter)

sudo bash
mkdir -p /syno/plex
chmod -R 755 /syno

Now mount there.

Also make sure a user plex exists on the Syno.
User plex there must have permission to read the shared folders.

@ChuckPa thanks for the response, but that didn’t seem to fix my issue. The directory seems to mount (I can see it mounted in cockpit) but when I ls the directory I get this:
plex@plex2020:/syno/plex$ ls
Library tmp_transcoding

When I browse the synology those files don’t exist… and when I mount the same file share to my Chromebook using the same plex user credentials, I can walk the file shares on the synology. For some reason, my linux install just can’t see the files once the directory is mounted.

Consequently, I just tried logging into the linux instance as root and I get the same result. No users on the linux PC can browse the synology files from CLI.

Any additional thoughts are appreciated…Thanks in advance…

That directory looks like the Plex share (which contains the metadata) and resides, by default, at /volume1/Plex.

May I ask why you’re looking to mount that on the Linux side?

if you remove sec=sys then having matching Usernames is required.
If you have sec=sys then matching UID/GID is required is required.

In either case, permission to access the specific shared folder(s) is required to be granted by DSM.
