Solved [Solved] Panic during boot when mounting root ZFS

When I boot my system, I get a panic as soon as it tries to mount the ZFS root. And I have no clue why or how to fix it.

I managed to boot from a FreeBSD-livecd and import zroot
Code: 
zpool import -f -o altroot=/mnt zroot
After that I could run a scrub
Code: 
zpool scrub zroot
But no errors where found. The filesystem was fine. At this point I could backup all important data. But I would really like to fix the problem.

After that I placed the disks (it's a mirror) into an identical system, to rule out any hardware issues with the original system. But no luck, still the same problem.

This leads me to the conclusion something is wrong with the ZFS root. But I don't know what, let alone how to fix this. Any help would be really appreciated.

Thanks in advance :)

Some details? Please provide:
  • the output of uname -a
  • some basic info on hardware (Manufacturer/Model, CPU, RAM)
  • the contents of your /boot/loader.conf file
Thanks.

After some trial and error, I narrowed it down to a SATA-cable. After replacing it, the server booted fine. I really hope this was indeed the issue. You never know for sure with these kind of problems :\
