Library scan - System.IO.IOException: Permission denied

I'm fighting with a really strange permission issue since one of the last server updates


in folder /volume3/AUDIO/ALEX there are almost 300 sub folders (each a different artist) again with multiple subfolders (1 per album)





          /[2012] Hot Cakes

               - 01. Every Inch of You.mp3

               - 02. Nothin's Gonna Stop Us.mp3

               - etc.


although everything was working fine before I can now only see 7 albums in my "ALEX" library - for all other folders I'm getting a System.IO.IOException: Permission denied error (see log below)

I already tried to completely remove emby server and installed it from scratch - even tried with a different user name and gave read/write permission for user embysvr to folder AUDIO

but that didn't work out either


any idea why the library scan is only working for 7 random folders but not for the rest?


(I'm running emby server on a Synology Diskstation)

Hi, the above error is for the real-time monitor. It won't affect the library scan, although if you have general permissions problems then that might. Have you checked the permissions of all sub-folders?


@@FrostByte may have some tips on this.

thanks a lot Luke & FrostByte. It was indeed a permissions issue. Don't know why, but somehow my embysvr user lost its permissions for almost all of my subfolders although I didn't change anything. Maybe this was due to some emby server updates? Nevertheless, everything is working fine again. Thanks for your help!!
