You do a new config, no need to format drives, just start the array after doing it, of course any zfs drives won't mount, but then just upgrade back to v6.12.

 

Also make sure you try safe mode.

I think I figured it out, I disabled dynamix cache directories and discs stopped constant reads and writes and have stayed spun down with docker and vms disabled. Hope this helps anyone trying to troubleshoot this. These were my settings when cache directories was enabled with 128gb of ram.

There have been some other reports but nothing conclusive that I know of, user that reported the initial issue with rc2 says it's solved with rc3, just a few posts above a user reported issues but now says it's working:

 

 

Some users reported that going back to v6.11.5 and upgrading back helped, others that it only helped after doing a new config with v6.11.5 and then upgrade back.

 

For now probably best to wait a little longer to see if more reports surface as more people update.

Today I took the time to try both of these methods. Downloaded 6.11.5 zip, swapped bz files, made bootable. Didn't/couldn't format drives when setting the new config up on 6.11.5 because of single disc zfs in array and zfs pools (all array and pool devices) so perhaps the new config never really started since the array never really started? Updated back to rc3 and still no spin down. Tried downgrade again without new config and then upgraded back to rc3 still no spin down. Currently array started on rc3, no smb, nfs, or external access. Docker and vm service disabled. Still getting constant reads and writes on all discs that hold data, much more reads and writes on the drive containing more data(50% capacity segate exos18tb vs 3%same drive). Interestingly enough backup server running zfs on all array and pool devices spins down perfectly after a new build and fresh install of Unraid directly to rc3.

Happy to share any logs, diagnostics, or follow any troubleshooting tips that might help. Im spinning up a backup server so i can offload/backup all the data on this one. But in the mean time fingers crossed for RC4 or figuring out the root cause 😀

And rc3 didn't help?

Still the same on RC3. I thought it was zfs doing its checksums and checks in the background

Interesting, there's a user that had issues with rc2 and says they are fixed with rc3, do they spin down if you do it manually? If yes do they spin back up immediately or after just a few seconds?

I've been experiencing this since rc2 with zfs. If I manually spin down disk 1 and 2 spin back up immediately even with docker service and vm disabled. Constant read and writes even with smb disabled.
