#
# DESCRIPTION:
# Once zpool set autoexpand=on poolname, zpool can autoexpand by
# Dynamic LUN Expansion
#
#
# STRATEGY:
# 1) Create a pool
# 2) Create volume on top of the pool
# 3) Create pool by using the zvols and set autoexpand=on
# 4) Expand the vol size by 'zfs set volsize'
# 5) Check that the pool size was expanded
#
