I had a Hardware failure recently where my CPU or Board died, since then I replaced both.

Now the problem is that all my pool devices are unassigned:

 

What would be the best way to restore the pools without losing data?

The diagnostics File:

biggie-diagnostics-20241124-1110.zip

The zpools look fine:

 

Can I import the zpools and Unraid will detect them as the right pools and assign the devices accordingly?

I would import them with:

zpool import -a

 

Any help is appreciated! I may be a bit overly cautious since I do not want to lose any data...

This won't work, but you can just assign the devices to each pool, assign them to each pool in the same order as zpool import shows, leave the pool filesystem set to auto and star the array, it will import the existing pools.
