Fairly new to unraid here. I recently copied roughly 7 tb of data using krusader from an unassigned device to a share. Now I see read on one drive in the array and write on another drive. The log confirms that files are moving from one drive to another. So far I have seen drive 2 move assets to drive 3 until drive 3 is full, then it begins moving assets from drive 2 to drive 4 until drive 4 is full. Now I am seeing it move assets from drive 3 back to drive 2. Any ideas why this would be happening? The share I copied to is also synchronized to another off site server using resilio sync, but has reached 100% sync so no new files should be overwritten through that. No other docker apps are running.

My current configuration is unraid 7.0.1

2x8tb parity

3x8tb array (drive 2,3,4, drive 1 slot is empty, I don't remember why I did this)

1x8th unassigned (will be added to array)

I don't follow what you mean, please post a screenshot of mains with read/write stats enabled and also the diagnostics.

Can you post that log along with your Diagnostics

Unraid never automatically moves files/folders between drives in the array so if this is actually happening then you must have started something else doing this. The diagnostics may show what but not necessarily.

Except for a new feature to empty a drive, which I assume OP didn't configure since it wasn't mentioned. The logs (from what?) showing the moves and diagnostics might clear things up.

Which might explain moving from drive 2, but not later moving back to drive 2.

Sure this is the entry I am seeing in the log. It is a continuous list of these entries as it moves files. Yesterday the log was showing the path as /mnt/disk2 and the read/write confirmed the data was moving between disk 2 and 4, now it is showing data moving from disk 3 to 2. which I can confirm because the available space and size of the share on each drive is changing.

Remove the Mover Tuning Plugin, reboot, and see what happens.

I will try that, however I added the mover tuner plugin after this problem started to see if there was something I could identify through the plugin. So I suspect it will not be different.

Unfortunately my system is now hanging on the reboot screen. I still had the log open which is giving me this over and over in between still copying files.

Remove Unbalanced also. You might have to do a hard reboot.
