Sorry, But i was able to dd zero's to the devices "zpool status"
gave for the incorrect zpool, and made it disappear. There are
two possible cases that could have made this happen

1. When I first created the zpool (zpool create zfsdata ...)
   I control-c'd the command. I ran it to completion the next time
   around.
2. Some of the disks I used, were part of a zpool of the same 
   name, but on a different system. I created a zpool containing
   those disks and some new disks

I am not sure if I can reproduce what I saw.
