I just rebuilt my server and upgraded to 6.0. I brought over nothing from 5.0. Parity sync completed and configuration is valid. Created a Docker image and installed Binhex Plex. All on a new SSD cache. I add the libraries and syncing of metadata begins. All artwork and text show up on the clients as it should. However, after leaving it for a few hours and coming back I noticed I can't get in to the PLEX web interface. The Docker says it's running so I restart PLEX. PLEX comes back but here is where it gets weird.

 

All the metadata text around my content is still there, but all thumbnails, posters, and artwork aren't showing up. I navigate through the cache to see if I can find any, but it literally seems to have disappeared. It just isn't there anymore. Rescanning the libraries doesn't do anything and it doesn't pickup any artwork. So I think maybe something might be an issue with Binhex PLEX so I delete everything from the cache except the image file and remove Binhex PLEX. Then I install Needo's Docker. I go through the same process and the same exact thing happens overnight. Any idea what could be causing this?

What are your host drive mappings?  How big is your docker.img file?

Wait a minute. It looks like mover is enabled. I never enabled it and assumed the data on the cache would just stay there and be at risk. I noticed this because it appears a share was created for my apps on the cache even though there is just one app right now (PLEX). Any idea how to disable the mover?  I think I need to do that and just start from scratch.

Under settings / Global Share Settings, you can set use cache disk to No.  (Or you can set your appdata share that you're using with Plex to be cache only under its share settings)

 

If you set use cache disk to No, if your path mappings are /mnt/user/appdata, you will have to change it to /mnt/cache/appdata to force the metadata to go onto the cache drive

Thanks Squid. Let me try that first.

You should create a share named appdata and in the settings for that share, set it to Use cache disk: Only. Then it won't matter if your other shares use cache and whether mover runs.

 

Then, put any appdata for any of your dockers as subfolders of that single appdata share. This is the way most are doing it, this is the way limetech intended it to be used, and this is what is assumed by many templates and tutorials.

It does appear to have been the mover that was causing issues. Now Plex seems to be operating fine. Thanks.
