How to stop slow spa_sync

[Amixus]

Greetings,

today my backup server got stuck after a restart. I don't need any help with data recovery or things like this. My data is save. My only question is how to stop the "slow spa_sync"to get access to the GUI.

Dose it help to format this 3 drives or is it better to detach and reattach them after the system is booted?

Looks like it's not finding a pool. Paste the output of zpool status using Insert -> Code.

Actually the server is now working fine. The problem is gone. The only thing I did was doing a break and afterwords everything went like a charm. Nevertheless I will format those disks. Creating and deleting folders within the GUI takes ages. There is something going wrong after I deleted a 100% full dataset.
