Moving just thumbnails and metadata usually doesn’t solve the whole problem.
It’s usually best, and definitely easier / less complicated, to move the entire PMS “AppSuppDir” (directory where PMS resides) to a new location.
How skilled are you with the Linux command line (1-10 scale) ?
I can show you what you’ll need to do.
If you’ll share where PMS is currently stored (default is /var/lib/plexmediaserver)
and where you want to move it to,
I’ll gladly show you how to do it easily & most efficiently.
Once it’s moved, we simply create a local configuration configuration file (a systemd override.conf file to specify the new location.
One procedure for moving and configuring is shown here:
The directory you use is your choice as long as you perform all the steps.
If you have questions, PLEASE don’t hesitate to ask.
PS: Given you’re having a space problem, I’d like to ask how big your databases are. Are they bloated / very large ? (this was a bug in PMS 1.41.6 & 1.41.7 )
