I can't see this working at all.  Even if the iscsi initiator presents the
new bigger size, the pool/vdevs/etc have all been created using a specific
'disk' size.  Rather than grow the target, can they carve off more space
and present you a 2nd LUN?  You could then add that as a 2nd vdev to the
pool...
