You need to have the zfs device visible in the jail, for this you need  
to use a devfs rule at jail-start which makes it visible in the jail.

See http://www.leidinger.net/blog/2011/05/19/how-i-setup-a-jail-host  
in the part "Ad­di­tional devfs rules for Jails"  
(devfsrules_jail_withzfs).

Bye,
Alexander.
