My 4tb cache drive keeps filling itself up with the mover action. I feel that this has something to do Plex Appdata not possibly pointing to the right area, however I cannot get it to fix itself.

 

Things I have tried:

1. Went nuclear deleting the localhost and photo-transcoder folder in Plex-Media-Server AppData (knowing it will recreate itself)

2. Change AppData shares to ensure Array -> Cache Move

3. Run NCDU from NerdTools to examine the Cache drive contents (It was mostly Media files, which is to be expected, however not sure why these appdata files take so long to transfer)

4. Turn on Mover logging

5. Disabled All Docker and VM services while the mover is in action (to fight any possible open files)

 

Example of Mover logs:

Aug 18 15:24:38 Bandicoot move: Moving "/mnt/cache/./appdata/Plex-Media-Server/Library/Application Support/Plex Media Server/Metadata/TV Shows/f/4d35b9c13787477c26a2ddf060bacd7b12260b6.bundle/Contents/_combined/posters/tv.plex.agents.series_7b4e34775154d2c7edad1e2a936fd2f418304794"  to  /mnt/user0/ 
Aug 18 15:24:38 Bandicoot move: 170397 files remaining from caches to array  3.8TiB
Aug 18 15:24:38 Bandicoot move: Moving "/mnt/cache/./appdata/Plex-Media-Server/Library/Application Support/Plex Media Server/Metadata/TV Shows/f/4d35b9c13787477c26a2ddf060bacd7b12260b6.bundle/Contents/_combined/posters/tv.plex.agents.series_38e5d7f858f98610239e9824e5de914985d13bd4"  to  /mnt/user0/ 
Aug 18 15:24:38 Bandicoot move: 170396 files remaining from caches to array  3.8TiB
Aug 18 15:24:38 Bandicoot move: Moving "/mnt/cache/./appdata/Plex-Media-Server/Library/Application Support/Plex Media Server/Metadata/TV Shows/f/4d35b9c13787477c26a2ddf060bacd7b12260b6.bundle/Contents/_combined/posters/tv.plex.agents.series_55135b6ce7fa18effe28ecacbc795bd5cb183cf4"  to  /mnt/user0/ 

 

These logs run endlessly for hours and hours and the " ### files remaining" will go down for a few hours and then jump right back up by 100,000 files, so no actual progress has been made over the last few days of Mover action. 

 

Remember these files have been deleted and the Unraid server has been rebooted multiple times.

I've also included the Diagnostic files.

The main problem is that other data on cache which is taking 3.2TB. You need to get that moved off cache.

 

Your diagnostics has a share with files on cache and configured to be moved to the array, but that doesn't show in your ncdu output.

d--a                              shareUseCache="yes"     # Share exists on cache, disk1, disk2, disk3, disk4, disk5, disk6, disk7, disk8, disk9, disk10, disk11, disk12, disk13

 

What do you get from command line with this?

ls -lah /mnt/cache

Thank you for you help.

 

I actually think the share did display on the NCDU command, it's just that the green highlight almost makes it not visible, which is the Data share which shows 3.2tb.

@jdhill777 You should remove the Mover Tuning plugin and then run mover manually.

That is a great idea and I can't believe I didn't think of that.

 

I've tried it and an hour in and the mover is behaving much more normal. Thank you for your advice! I think the mover tuning plugin is still not game-time ready for 7.0 yet.

Also you typically want your appdata only on cache, not being moved to slow drives.

With the settings shown in the screenshot then mover will attempt to do this once space has been made by flushing the 'data' share to the array.

Nothing can move open files, so you may need to disable Docker in Settings to get all of appdata moved to cache.
