[SOLVED] Thumbnails not showing after moving Plex Media Library

Server Version#: Version 4.22.2
Player Version#:
Hello, I had an issue with my plex media library filling up my boot partition, so I followed the instructions here I can play my files, but it no longer displays the thumbnails for my locally stored files.

I am running Mint Linux 19.3 Any help would be greatly appreciated.

Need more info please.

From where/what to where/what.

Is this just a case of having moved from /var/ilb/plexmediaserver and not changing the permissions fully?

Correct, I moved it from the default location /var/lib/plexmediaserver to /home/plexdata. I believe the original location was owned by root. I changed the new directory to be owned by my userid & group.

Originally, everything was owned by plex:plex.

Now, you should have everything owned by your user & group
with both specified in the override file.

Is that done by the Umask command at the end of the override file, or do I need to add something else?

In my procedure,

Step A - Declare the User & Group to use

#  These values are only needed if you wish to change user & group
User=chuck
Group=strange

Step B - Change ownership to match (must be done under sudo permission)

# now change ownership
cd /home/plexdata
chown -R chuck:strange

My file looks like this

#
# Customize Plex's config
[Service]
Environment="PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/home/plexdata/Library/Application Support"
#
#  These values are only needed if you wish to change user & group
User=chris
Group=chris
#
# This is needed to change the default umask 
UMask=0002    # this must be 4 digits of octal 

And my plexdata directory looks like this:
drwxr-xr-x 3 chris chris 4096 Feb 29 20:03 plexdata

Thanks for sharing. This makes the solution simple:

sudo chown -R chris:chris  /home/plexdata

Now everything in /home/plexdata is owned properly and ready to go.

OK, thanks I ran that from the command line, reloaded the daemon & restarted plex. Do I need to rescan he libraries, because I’m still not seeing the thumbnails.

If you copied it correctly and completely, you have everything as before.

Which method was used? “tar” or “cp” ?

tar as outlined in the tutorial.

Then everything should be as it was.
Tar would have coughed errors in the process if there were any.

I will ask, just to confirm, this was done with PMS in a stopped state?

No, I did not think to stop PMS :frowning:

OOOPS.

  1. Stop what you have now.
  2. Delete /home/plexdata/Library (rm -rf)
  3. Do the copy (tar) again . :slight_smile:
  4. Change the ownership again after the tar extraction is complete and the data copied.
  5. Start Plex

I think I’m in trouble then. When I originally tested it I thought worked, so I deleted the original /var/ilb/plexmediaserver file :frowning:

There is recovery… DO NOT PANIC

For each of your library sections:

  • Force a Refresh All Metadata
  • Wait for it to complete
  • Advance to the next section.

Awesome! I will do that. Thank you so much for all your help!
