File Permissions issue

[agottschling 2]

Hey all, I've hit a brick wall here. Emby is constantly complaining about not being able to access NFO files when it runs a library scan, and I assume that there are some other permissions issues as well because when I try to view details on an episode sometimes, the app will seem to hang. 

When looking at the server logs, this is an example of what I will get:

Also, Here's the error from the browser's javascript console when I try to browse info for some episodes (BTW. when this happens, I can't find anything out of the ordinary in the server logs):

My setup is as follows:

I have Emby running on a spare PC i3, 8gb ram, etc. 

All my media files are on a Buffalo Terastation, in the same share which is mounted to a folder on the filesystem (can't access anonymously, that's disabled). It seems like I can read and write on the command line, but I can't really tell if everything is being synced completely on the NAS side.

 

Any ideas?

Hi, you need to ensure Emby has write access those folders. Emby Server runs under a system user called Emby, so you need to make sure that user has write access. Alternatively you can also turn off saving of nfo files and then you won't see these errors in the log file anymore. Please let us know if this helps. Thanks.

Hi Luke,

When I mount the folder on the filesystem in /etc/fstab It's mounted as rw, and I've set the owner and group to the emby user. I can provide the mount line in fstab if needed. 

The strange part is that is only seems to happen with some files.

Any ideas?

[Luke 37095]

Hi there, yes can you provide the mount line? Are you still running into this?

[agottschling 2]

Hey Luke,

I've long since decommissioned that system that was running emby and have even decommissioned the NAS that I was using at the time.

I've moved everything onto Windows Server and a Synology NAS and haven't been having any issues with that.

Sorry I can't be more help

Thanks for the feedback.
