Server Version#: Ubuntu 16.04.7 LTS (GNU/Linux 4.4.0-194-generic x86_64)
Player Version#: Version 1.20.4.3517
I have Plex Media Server running in a headless HP server (command line only) with an SSD boot drive and two 4TB data drives containing the media. There is quite a lot of data on the drives, 1325 movies, 3000 TV Show episodes and 1600 music albums.
My SSD is now full with metadata (in excess of 85GB) so am looking to move this to one of the two 4TB disks. I found an old process from 2015 that apparently worked for Ubuntu 14.04, but this does not work for V16.04, not sure if it is a permission thing or if it is because the process has changed.
Please can someone publish a clear guide on how to do this as I cannot be the only person to need it.
Thanks
If I’m understanding your desire correctly, the answer should be in here:
Specifically: Moving Plex’s metadata (Library) directory on systemd based systems
So I tried to move the metadata using the following and Plex no longer starts
Mounted the two disks in /disks instead of /media

Moved the metadata to /disks/media1/plexMD and set owner to plex

Created the override file in /etc/systemd/system/plexmediaserver.service.d, owner root:root and also plex:plex, tried chmod to 777 too
Customize Plex’s config
Identify this as a service override
[Service]
Move the data directory
Environment=“PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/disks/media1/plexMD/plexmediaserver/Library/Application Support”
These values are only needed if you wish to change user & group
#User=chuck
#Group=chuck
This is needed to change the default umask
#UMask=002 # this must be octal - See warning below
there is no point me putting the metadata in /home as that is full. the only thing I didn’t try is to run plex with my user and group, but that shouldn’t be necessary
First and foremost:
Since user plex:plex is running as the PMS user,
Did you make certain user plex:plex minimally has R-X for /disks, /disks/media1, and /disks/media1/plexMD ?
Then, after that step,
Is user plex:plex owner of the new plexmediaserver directory and all below it?
(there is a step in my procedure where you force-set the ownership again to make certain tar/cp didn’t break it).
In all sincerity, a step was missed somewhere. The procedure works when followed step by step
I will help you review if you wish.
Thank you, the problem seemed to be that plex didn’t have permissions to /disks
I checked by creating test.txt and then running
sudo -u plex test -r /disks/media1/plexMD/test.txt
The with -w for write and -x for execute
Glad you found it!
