I just wanted to install plex on Unraid after my experience from the Truenas app, but unfortunately it is a real hustle for me.
I started with the image from binhex: "binhex/arch-plexpass" and had problems setting the correct permissions from different shares.

 

I used this string for extra parameters: --device=/dev/dri --mount type=tmpfs,destination=/tmp,tmpfs-size=10000000000 --no-healthcheck
from this tutorial .

 

After that I set all paths: CONFIG ->  /mnt/remotes/Plex_Database  (a ssd pool on my truenas vm with a user PUID=GUID=1044 and the mountcommand also mounts with the same PUID,GUID). 

 

MEDIA -> /mnt/hyperion/hyperion media/media (my secondary pool on unraid only for media)

TRANS_DIR (as a system variable) -> /tmp (as stated in the tutorial above, so that the ram is used as a directory but only with 10gb instead of 20)

 

HW_Encoding -> /dev/dri (I added this one myself to give the docker access to the GPUs for the future)

 

My plex ui isn't able to play ANY titel no matter if movie or tv-show. I converted one title from mkv to mp4 which didnt help. The source of the files are *LEGAL* downloads (of course) and a few rips. 

 

If I try to use the settings button during the initial loading I get: "Unexpected errors during playback. Please visit our forum if you continue to experience problems." (translated from German)

 

If I wait I either get :  "An error has occurred while playing *movie name*. Error code s1003 (network)"
OR:   "This server is not powerful enough to convert videos. "

... with and without HW-Encoding turned on ...  

I am using a 13900KS, Unraid 7.0.0-rc.1, 128GB ram of which 50-80 ist mostly occupied depending on the load.

 

These are a few error I found in the logs:
"ERROR - [VoiceActivityDetectionManager] MDE: video has neither a video stream nor an audio stream" and I think this one can be ignored, but I am not sure. 

"ERROR - [Req#1fc2] XML: Database exception: sqlite3_statement_backend::prepare: locking protocol for SQL "
"ERROR - [Req#212a] Unknown metadata type: folder" 
(The log is not anonymus, that is why I am not attaching it)

My SMB layout is very niche, which is why I wanted to use the Unraid forum first before proceeding to the plex forum or reddit. 

Any ideas what I could have done wrong ? I thought all permissions are set, because plex was also avaible to prepare all the metadata.
Could permissions be the problem ? I wouldn't think plex has problems with the mkv format.

 

Thanks in advance  

 

 

 

SOLVED ! See here: 

 

The problem was the SMB share !
