Plex container constantly starting

1st Official Post

    Hello chaps and chapettes,


    Total noob here having some issues with plex in portainer.
    Having totally lost my server on Thursday I'm rebuilding from the ground up in OMV 5 using portainer.
    I followed techno dad lifes video tutorial for plex setup but when I deploy the plex container log constantly keeps saying:
    Starting plex media server
    Over and over again and I have no access to the plex gui
    Any ideas what I've done wrong?
    I suspect it might be a permission issue but I'm really noob at this stuff

    I'm using linuxserver/plex:latest as per techno dad's video.
    The container boots but rather than giving me any gui it doesn't do anything.
    The log prints the following:

    Also, this is on a hp microserver so should be amd64 I believe?


    Also fouind this in the local plex logs

    I found the issue. I have just setup UnionFS , the config and transcode dont like to be int he pool so have simply placed those volumes outside it.
    Thanks for taking the time to read and help though.
    Merry Xmas all

    Changed the title of the thread from “Plex portainer constantly starting” to “Plex container constantly starting”.

    Thanks, just stumbled across this...it's weird, I haven't had an issue until the other night, and then I lost 4 of my Containers...including Plex. It seems that I'm getting the same errors.


    I'm not really sure if I undrestand the issue, but i do use UnionFS as well. I thought I had my config and transcode with direct links, but maybe I should just double check that...

    I just happened to experience this same issue after migrating to OMV5. I have 3 drives pooled, placed Plex's /config and /transcode in a share in the pool and it did not worked. Now, I know that I have to put those folders outside the pool, but how? I am considering two options:


    1. Put both folders in one drive of the pool and point Docker directly to them (use the drive_ID/config instead of pool-mount-point/config). However, I am not sure if that might mess up with the pool. I tried that already and it worked, but I ended up with two folders with identical drive names under /srv: one with the data from the pool and another one with only the Plex Database. Any ideas or recommendations?

    2. Put both folders in the OS drive under /var/lib/Plex. I am using a 64 Gb SSD and the database should not be that big (circa 3,5 GB)

    3. Any other suggestions?


    Thanks in advance

    Edited once, last by Eryan ().

    I would just do a Plex direct installation on OMV5.

    It gives you better performance and avoid latency especially the transcoding process.

    It worked for me on OMV5 and Raspberry Pi 4.

    I have been running Plex on OMV for more than five years on what I describe as fairly meager hardware, both direct and in docker. I have never noticed any difference between direct install and in docker performance. Either you have enough CPU to meet your transcoding use case demands or you don't.


    What does better performance mean anyway? What is this latency you mention?
