#
# Description:
# Once set zpool autoexpand=off, zpool can *NOT* autoexpand by
# Dynamic LUN Expansion
#
#
# STRATEGY:
# 1) Create a pool
# 2) Create volumes on top of the pool
# 3) Create pool by using the zvols and set autoexpand=off
# 4) Expand the vol size by zfs set volsize
# 5) Check that the pool size is not changed
#
