Perpetual permission issue with second NAS

[strager 18]

OK - so I have Emby running on a TerraMaster using TOS3. 

I've been trying to connect it to a second NAS (a WDMyCloud Ex400) that has a different library on it.

I can't mount it in Emby because the My Cloud requires a username/password and apparently Emby doesn't support connecting to a Samba share with one.

I tried mounting it using Remote Share on the Terramaster as NFS, but it tells me it doesn't have permission to read the share.

I finally mounted it as a samba share, but now it appears emby has Read permissions but not write permissions to the drive. The "admin" account on the terramaster can access it just fine.

I tried SSHing in and Chmoding the file (777 with a big 'ol -R to make it apply to all the subfolders) but no luck - the 'emby' account still can't write to it. 

No matter what I try to do, I can't write. Is there a way I can change Emby to use the "admin" account on the terramaster instead of it's own emby account?

Here's an example out of the logs:

Is there an option to mount the shared folder mapped to a specific user? This screenshot is from TOS5 and in the NFS section but maybe there is a similar option for you

Also you could try doing a chown -R 999:999 on the folder (no owner) so anyone can access.

Give these a try and let me know if you have any luck

CORRECTION TO MY OP: I apparently am on TOS 4.2 not TOS 3. Not sure where I saw 3 before.

 

Thanks for your answer @squarepeg - There was no option to mount as a specific user that I could find. I also don't have that "squash" setting or "asynchronous" anywhere.

These are the only options I have for NFS:

 

 

I tried to chown and it did not make a difference either

@strager did you figure this out?

[strager 18]

Actually @LukeI never did... I got it to somewhat work but its still throwing the permission errors. Here's a recent one:

@stragerit appears you enabled saving metadata to nfo files but the server is being denied write access to your media folders. I would suggest resolving those permissions or just turning off nfo file saving. Please let us know if this helps. Thanks.

[strager 18]

That's the bulk of the issue. I can't seem to give Emby permission to write. I've tried everything I can think of, but there seems to be no way to give it credentials and even when I changed the permissions on the folders to 777 it still gives the error. 

[Luke 33618]

@stragerdid you figure out how to set the permissions?
