Media not found when using CIFS between 2 separate Synology DSNs

[mitelford]

Server Version#:1.42.2.10156-700010156
Player Version#:
I have Plex Media Server installed on a Synology NAS. Everything works as expected with local folders & files.

The Drive is low on space so I have a second Synology NAS on the same LAN with a folder containing more video files.

On the PMS I have set up a remote connection (CIFS) to the second ‘slave’ NAS.

In File Station the remote Folder(s) is available and can be navigated, video files can be downloaded and/or played.

I am guessing this is a Plex Permissions issue.

I cannot find where I can set the permissions for the remote CIFS folder to allow Plex to access it.

If I go to the permissions for each individual folder in the CIFS folder I can create a new user for PlexMediaServer but it fails with a Windows ACL error and there is surely a better way to set permissions rather than on each and every folder.

This has all worked before, I am confuse as to what has changed.

Any ideas?

If you’re sharing data between Synology machines, use NFS.
CIFS is Windows. Synology is Linux. Linux ↔ Linux needs NFS

[mitelford]

When I try NFS I get ‘Connection failed. Please make sure the remote server is accessible via NFS’.

NFS is running on both NAS. I have tried with both NFS v3 & v4.

Both NAS are on the same LAN & IP Range ,i.e. 192.168.2.110 & 129.168.2.112

Firewall is not running on either NAS.

Did you also export the shared folder (NFS rule) ?

Control Panel → Shared Folder - EDIT the shared folder - CREATE a rule to export the shared folder ?

If you don’t, there will be nothing to share and you won’t get a response.

I have done that.

192.168.2.110 is the PMS.

I set this NFS Rule on the second NAS which is 192.168.2.112

On the 2nd syno, go into the permissions,

Highlight the shared folder - Right-Click → Properties → Permissions

Give permission to Everyone (Read)

Apply to this folder , sub-folders, and files.

Synology is VERY odd & secure with permissions between machines.

[mitelford]

I’ve added the user ‘Everyone’ to the Folder on the second NAS and given it Read permissions.

On the PMS NAS the remote folder has the Everyone user but has Read/Write permissions.

The Folder on the PMS NAS is empty as you suggested.

Still can’t past the Connection failed problem.
