Transcoded stuff didn't work anymore, direct play works

Plex Media Server Desktops & Laptops

Server Version#: 1.21.2.3943
Player Version#: Webplayer via Chrome

After copy the database (/var/lib/plexmediaserver/) to another disk I do a symlink to the original directory. It’s the hole database I copied.
After that the database and mediathek works fine, everything is as normal. But if I try to watch something from the browser or anything that has to be transcoded, it loads forever.
Even a job to optimize and transcode media didn’t work, the same error.

I found a similar topic that said I should delete /var/lib/plexmediaserver…/Codecs/EasyAudioCodec (or something like this) so Plex can download it again, but it didn’t work. It’s the same error as before.

That symbolic link, specifically the target partition, is biting you.

You’ve placed PMS on a partition which was not mounted with the exec option in /etc/fstab

The codecs are shared libraries.

Shared libraries, being executable code, must have execute permission at the file system level (mount point)

This is why you need to add exec to the mount option for that file system.

Thank you very much!

So I cannot link everything or I have to put the exec command on the specific partition.

Have a good day.

@Kampfkuchen

Please read here. I have provided a guide how to do this.

Option F shows how to address the issue you have.
I recommend moving the library using the accepted systemd technique.
