Also remember the problem with the other pool was just a bad VM config issue, nothing else.

Ok, now I guess I know the problem. Of course it's my fault again as every time ...!

There must be any old config information that unraid was using in the latest update to 7.1.4.

When removing my Gaming pool and rebooting two times to check if the drives come back again. I got an error message from unraid.

Disk Location: nvme3n1

Alert - Device failure

Samsung SSD 980 PRO 500GB S5GYNF0W122040R

But this disk doesn't exit for months, actually for years anymore on this unraid installation.

Probably my fault, as I am using similar names for the pools?

I also had similar problems with the upper and lower case of shares in the last updates that don't exist anymore, this problems always came back, but were easy to fix.

I guess best way is to have a completly new unraid installation.

So, what is the best way to fully reinstall unraid on an existing stick with an existing licence?

You can boot with a new install and see if all devices remain online.

It's really weird and I stopped searching for the problem, as it looks like it can damage the Hardware!

When I was swapping the two nvme drives, one of them was already bricked or gone. No problem I got a warranty replacement.

But I guess this explains why the problem at that time was following the drive.

So after new installation of unraid on the stick the problem came back again. But I guess this was due to the config files for apps and vms that still existed on my drives.

I took the original motherboard on which the problem started. I deleted the nvme drives, added new unraid array drives and zfs pool drives without any changes again.

After that everything worked fine without any problems since. Of course I am still busy restoring my data from backup and configuring vms and dockers manually again.

But it works and at least for me it was the best solution.

Best regards
