Are you sure? It seems like everything is working now. The UI glitch is a bit strange but after a while the drives etc appear. I was also able to recreate the VM without a problem.
OK, here it is
awk: cmd. line:1: (FILENAME=/kellerbak-diagnostics-20220518-1941/logs/syslog.txt FNR=35) warning: Invalid multibyte data detected. There may be a mismatch between your data and your locale

The SSD was not the cache. It assigned it to the VM. Dunno why the VMs gone but it should be easy to recreate it unless you know a better way to restore the settings.
After restarting another time, things look a lot better. I was able to start the array and everything seems okay except there are blue text boxes everywhere and my VMs are gone. Could attached the diagnostics file this time

I switched my backup server to 6.10 which seemed to have worked okay until I started the upgrade of the certificate. Now my whole array and all drives are missing.
Does that mean it is save now to go to 6.10? I remember people having problems especially with Docker on ZFS (Dataset, apparently ZVOL seemed OK). Can anyone confirm?
