Help with setting permissions on raspberry pi

[Pancake2 0]

Hello all, 

I'm not a complete beginner, but I need some help with setting the permissions on my mount on raspbian. 

I have a USB hdd owned by root, but with 777 permissions. Emby server accesses it OK with the emby user. 

However, I keep getting lots of errors with the configuration backup plugin, although the files seem to still be copied. 

My logs get flooded with messages like this:

emby needs to have write permission to this folder

I gave it 777 permission with chmod, shouldn't that work? 

[mastrmind11 722]

what is the output of ls -l on that directory?

well it's clearly writing the files, so it's not that directory.  how about the permissions on /opt/emby-server/system

Ok, I fixed it by editing the fstab file and setting emby as the owner.

After restart, I'm still getting one error when emby starts, is it related?

Please attach the complete log file. Also what problem are you having?

Actually I'm not having any problems, I was just checking the logs and got curious with that error.

Here is the log requested. The error seems to happen a couple of times.

Ok it's nothing to worry about. We'll clean up that logging. Thanks.
