Ubuntu 18.04.03, Docker, Plex, Not finding files

Hi all,

I’ve been attempting to set up a new Plex Media Server using a intel nuc running Ubuntu 18.04.03 and Docker, mounting a share from my ReadyNAS 316 onto the NUC and passing it through to docker.

docker-compose.yml 
---
version: "3"
services:
  plex:
    image: linuxserver/plex
    container_name: plex
    network_mode: host
    ports:
      - 32400:32400
    environment:
      - PUID=1000
      - PGID=1000
      - VERSION=docker  
    volumes:
      - /mnt/media/videos/library:/config
      - /mnt/media/videos/tvshows:/tvshows
      - /mnt/media/videos/movies:/movies
      - /home/greg/Plex/transcode:/transcode
    restart: unless-stopped

I’ve mounted the share correctly as far as I can tell. I can see the mount from the terminal,

greg@machine:/mnt/media/videos/movies$ ls -larth
total 0
drwxrwxrwx 2 greg greg 0 Oct  3 17:56  Toy.Story.2.1999.1080p
drwxrwxrwx 2 greg greg 0 Oct  3 18:01  Toy.Story.1995.1080p
drwxrwxrwx 2 greg greg 0 Oct  6 01:00  ..
drwxrwxrwx 2 greg greg 0 Oct  6 01:22  .

and if I run docker exec -it plex /bin/bash and look at the mounts, I can see that the files are present within the docker:

root@machine:/# cd movies
root@machine:/movies# ls -larth
total 4.0K
drwxrwxrwx 2 abc  abc     0 Oct  3 16:56  Toy.Story.2.1999.1080p
drwxrwxrwx 2 abc  abc     0 Oct  3 17:01  Toy.Story.1995.1080p

Furthermore when I’m in the Plex GUI I can see the folders and the files (screenshot below) when selecting the areas to scan for a library - however after multiple attempts with changing anything I can think of it’s not finding any of the files, it seems it can see the files, I’m wondering if there’s something permission wise I’m missing, or if anyone else has any thoughts on what might causing the problem?

Many Thanks.

Have resolved this, some digging in the log produced an error for SQLITE

ERROR - SQLITE3:(nil), 15, locking protocol in "PRAGMA cache_size=2000"

Seems plex didn’t enjoy having the config directory stored on the share, moved it to a local directory and it found the files instantly.
