Hello guys and gals!
After trying to solve my problem without any success, I wanted to share it with you guys since I'm not too experienced with OMV/Docker/Plex.
I'm hosting my own media server with OMV and running Plex via Docker on a mini desktop, which I have set up about eight months ago.
Everything good so far.
Then I ran out of space so I added a new SSD to my system and that's where I'm stuck.
I added/mounted the drive as I did before but I am more than certain that I did something wrong since Plex is not showing the newly added files from the new drive.
(Thought it might be because of mergerfs but if I just use the new drive via the path in shared folders, same problem)
I've updated Plex and also tried changing the movie names just to be sure.
Also what I have noticed, when I switch the path via shared folders, I can see the different content off the different drives in my file explorer but on my Plex-App it stays the same (the old one).
I don't know if it is because of the mount setting but I wouldn't know how to change them.
Thanks in advance.
Edit:
I have noticed that my Plex container has the old path as a mount even tho I have changed it in "files" and restarted afterwards.
Edit 2:
I have created a separate shared folder which is visible on my file explorer but Plex can't find it in the library.
