      Description

      Server went into reboot loop, it would try to mount the pool named tank and it would reboot right after. I removed the disks, and the server would complete boot. Any attempt to mount the XFS pool resulted in a kernel panic.

      Was able to export the pool.
      Cannot import the pool.

      I have tried to just normal import and readonly and various options and ones below all result in a Kernel Panic..
      "zpool import tank""zpool import -o readonly=on -N tank"
      "zpool import -FX -N -f -o readonly=on tank"
      "zpool import -F -m -o readonly=on -f tank"

      I did also run this which aborted itself and stopped after an hour or so.
      root@Monster# zdb -e -bcsvL tank
