You can see that your pool was successfully created by using the zpool list command:

freebsd# zpool list
NAME   SIZE   USED  AVAIL    CAP  HEALTH  ALTROOT
zfs   3.97G   234K  3.97G     0%  ONLINE  -
			

Pools are destroyed by using the zpool destroy command. This command destroys the pool even if it contains mounted datasets.

# zpool destroy tank
			

Destroying a Pool With Faulted Devices

# zpool destroy tank
cannot destroy 'tank': pool is faulted
use '-f' to force destruction anyway
# zpool destroy -f tank
