Update 2:I have and had (!) full access to the media folders on Volume 2, though! Emby Server App can't find media folders. So I installed PLEX for testing. And I have full access to media folders on my NAS when I create a new library on PLEX Server. Seems Emby is buggy.
The problem is solved. It was a database conflict, not permissions. Everything works now. I got help in Emby Forum.
