No.
 
You can set the share use cache setting to "prefer", then run the mover, files can't be in use or they won't be moved.

Do you mean it's unassigned? If yes the right place to ask would be in the existing UD plugin support thread, but you just need to click on it.

Yes, just assign a new parity disk and start the array.

If you're using macvlan for that update to v6.10 and change to ipvlan.

Cache filesystem is corrupt, best bet it to re-format, if there's any important data there you can try these recovery options.

If it's happening with multiple disks, and since and understand the cables were replaced number one suspect would be the backplane, after that the controller itself, not the firmware, AFAIK that firmware has no known issues, and it's same I'm using, though if it it was the controller I would expect errors in all disks.

Try the 2nd option, btrfs restore.

Problem with the onboard controller, quite common with some Ryzen boards, usually under load, look for a BIOS update and if that doesn't help use an add-on controller, or a different board.

There are read errors with multiple disks, first thing to do is to update the LSI firmware, all p20 releases except latest one (20.00.07.00) have known issues.

Reboot, if it still doesn't start after that post the diagnostics.
 
 

Set pool slots to one and XFS will be available.

Enable system notifications so you're notified immediately when there's a problem.
 
Problem itself looks more like a power/connection issue, replace/swap cables to rule that out and as long as the emulated disk is mounting you can rebuild on top.
 
 

Problem is caused by only having one array disk with btrfs, this makes parity appear to have a valid btrfs filesystem and generates an error during device scan:
 
Mar 22 10:59:47 RizzoUnraid emhttpd: /mnt/cache_ssd ERROR: cannot scan /dev/sdl1: Input/output error  
Though strange that it doesn't happen with rc2, in any case best way forward to avoid this now and in the future is to either have more btrfs arrays disks on convert disk10 to xfs like the rest.

Sorry missed your first reply, damn forum bug, to separate the devices you can do this:
 
-stop the array
-disable VM/Docker services
-unassign the devices from both the docker_pool and the vm_pool
-start array
-stop array
-assign both devices to the docker_pool (there can't be an "all data will be deleted" warning in front of any of the pool devices)
-you can re-enable VM/Docer services
-start array
-stop array
-unassign the device you want to remove from docker_pool
-start array, wait for the btrfs balance to finish, once that's done
-stop the array
-assign the removed device to vm_pool
-start array
-vm_pool will be unmountable, format to start using it
 
 
 

Check/replace cables on disks 1 and 2 and post new diags.

You can preserve all, then just un-assign disks 6 and 7, less work and also less chance of making a mistake.
 
You can assign them as parity immediatly, but you can also start the array without them first if you want, either way all data on the remaining data disks will still be there.
 

Disk dropped offline, could be a connection/power problem, could also be a bad controller, replace/swap cables on that disks and if problems persist it's likely the controller.

Run a correcting check then a non correcting one to make result is 0.

Cache filesystem is corrupt, there are some recovery options here.

Just replace or swap with another and see if the problem goes away/follows the cable.

Please use the existing plugin support thread:
 
 

Change the onboard controller from IDE to AHCI/RAID.

Lots of data corruption being detected on both pools, start by running memtest.

Likely from the syslog server, check settings or disable if not needed, and delete the files.

Diags would be better but screenshot suggests drives were formatted non-encrypted, assuming there's no data there insert the key you want to use, start the array and re-format the drives.
