When I remove one of the DATA pools the machine will boot. I've tried exporting the pool and it doesn't help. While the pool drives are unplugged
I can boot the machine without issue. I've then run "devfsadm -C" to remove device entries.  Even then the machine won't boot with the drive
connected. After the OS is booted I can plug the drives in. They aren't visible via format until I run devfsadm again. The errors got me to
thinking there was something in the boot sector that was confusing my oldish MB and the MB was trying to boot off of one of those drives I used dd
to overwrite the MBR with no success. I'm thinking of just going and using dd to write /dev/zero over the entire drives. There's nothing on those
drives that I care about since I was just using them to play with different permutations of zfs and zones. Things like mounting filesystems in
zones, etc.
