When you add your folder(s) to your library in Plex, what does it show? For example, here’s mine:
Can you provide a similar screenshot? Is it the “Video” directory (or sub-directory) which you’re adding to your library?
Assuming that that is a directory listing of your /plexmedia directory, everything is owned by root. However, your permissions are set to 777 (readable and writeable by the world) so user ‘plex’ should have full access. There are things we can do in the fstab to trim down those permissions a bit, but as it is I believe Plex should have full access.
I’m using Docker, I do see the volumes that I configured in the installation, but not the ones I’ve mounted by following the guide…
both left side and right side are at the root of the folder…
I think I’ve made it!
I’ve rebuilt my Plex Docker and added the “plexmedia” mounted folder as the volume of my TV and Movie path, now I can see the External hard drive.
Also, be careful with volume maps in your Docker config. You’ve got /plexmedia mapped twice, once to “movies” and then again to “tv.” Do you have sub-directories under /plexmedia where your TV shows and movies are stored? If so, map those paths to your container. Better yet, just map it once and point your Plex libraries at the appropriate sub-directories.
