My guess is that you wiped the ZFS metadata that made the disk part of a
mirror and added it to the pool as another stripe.
It would help if you posted the relevant console session -- prompts,
commands issued, output displayed, etc...
Please run the following commands and post the console session,
substituting $POOLNAME as appropriate:
# zpool list $POOLNAME
# zpool status $POOLNAME
