Hi Harry.

A couple of different options:

1)  give your account zfs permissions (tank is the pool)

zfs allow -s  @adminrole 
clone,create,destroy,mount,promote,quota,receive,rename,reservation,rollback,send,snapshot,userprop 
tank
zfs allow harryp @adminrole tank


2)  use password less sudo for that use account.  In sudoers file add this:

harryp ALL = NOPASSWD: /usr/sbin/zfs


Have a great day!!
