Hello. I am running out of space on my OS volume on my QNAP TVS-h1688X. Most of this space is taken up by Plex, over 3TB, which I assume is mostly thumbnails etc, in the Plexdata folder. If I migrate this app to another volume, does this data go with it?

I have serious doubts that your thumbnails or databases are taking up 3TB of storage space… If so, there’s something terribly wrong with your system/setup. I would thoroughly go through to see exactly what is taking up so much space… For instance the databases MAY get as high as 1-2GB but even tha…

Yeah… I second @kazz3r24 here… something seems off even accounting for thumbnails. If you’ve had Plex running for a long time and switched between locations occasionally you might have some cruft you could clear out. You might give this tool a try: DBRepair Good place to start for some cleanup of…

Thank you. I do have quite a large Plex library of around 400 TB. It has been running off of this machine for about a year, previously migrated from another QNAP instance. I am working on getting some folder sizes now, but as it’s running, Plex Media Server\Media is approaching 1 TB

When you use App Center’s Migrate To function, QTS/QuTS moves the physical server instance (under .qpkg) to the new volume As PMS (re)starts , I look for a PlexData shared folder as I always do. If the shared folder exists, I get the current location (.qpkg) and then create the appro…

Supplemental to the relocation question. Please use FileStation Navigate: `PlexData / Plex Media Server / Plug-in Support / Databases Please screenshot the sizes of the DBs. (we’re suspecting you have bloated databases from 1.41.7 problems)

Here is the requested screenshot [image]

@orgetorix Thank you. Do you have an idea about how many items PMS has indexed and matched ? I’m asking only to make certain your DB should be that big. Otherwise, it looks good. As was suggested above, the next suspect are all the temp files PMS “forgets” to cleanup when it’s done with …
