Cannot restart PMS in Docker

Server Version#: 1.25.2.5319
Player Version#: 4.72.0
NAS: Synology DS1019+, DSM 7

Hello, it’s me again (already)! This time with another problem, hence a new topic.

So I just migrated PMS from the Synology app to Docker with the docker run command from the following topic:

The container works fine until I stop it and want to restart it - because I cannot restart it. Docker always shows me this error: “Unable to perform this operation, possibly because the network connection is unstable or the system is busy. Please try again later.”

The culprit here seems to be how the /volume1 is mounted. In the line for this entry in the container configuration there isn’t anything in the “File/Folder” column.

As long as this entry is there in the configuration, the container won’t start again. It only works on a fresh reboot of my NAS if I created that container with the --restart=always parameter. Once I stop the container again and try to restart it, it won’t work again.
Now if I stop the container and change any setting and apply my changes, the line with /volume1 vanishes from the configuration. I then can start the container just fine but then I can’t play any media because PMS can’t find it anymore.

Is there any (known) solution to this problem?

When asking for help with docker it is a good idea to post the full docker run or docker compose file you used to create the container.

As I said it was the command of the post I linked. Just a little altered to my preferences but that shouldn’t make a difference.

But okay, here it is:

docker run \
-d \
--name Plex-Media-Server \
--restart=always \
--network=host \
-e TZ="Europe/Berlin" \
-e LANG="de_DE.UTF-8" \
-e PLEX_UID=297536 \
-e PLEX_GID=297536 \
-h DockerPlex \
-v /volume1/PlexMediaServer/AppData:"/config/Library/Application Support" \
-v /volume1/PlexMediaServer/AppData/tmp:/tmp \
-v /volume1/PlexMediaServer/AppData/tmp:/transcode \
-v /volume1:/volume1 \
--device=/dev/dri:/dev/dri \
plexinc/pms-docker:public

I fixed it myself. I just moved all my media files to /volume1/PlexMediaServer/AppData/Medien and mounted that path in the Docker container. Then I just had to alter the paths for my libraries. Now I don’t need the /volume1 mount.
