Scenario:

ZFS pool1:
Mirror
/dev/ad0 - 250 GB
/dev/ad1 - 500 GB

EXT2 disk which is mounted at /mnt/olddisk :
/dev/ad2 - 500 GB

1. Delete the mount point of /dev/ad2 and delete the disk in the disk management.
2. Re-add the disk in the disk management as a ZFS volume.
3. At the console type: zpool replace pool1 ad0 ad2
4. ZFS pool is updated and after reboot 500GB are now available for pool1
5. Under disk management remove /dev/ad0 then re-add as a UFS disk
