# ID: zpool_expand_002_pos
#
# DESCRIPTION:
# After zpool online -e poolname zvol vdevs, 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
# 4) Expand the vol size by zfs set volsize
# 5  Use zpool online -e to online the zvol vdevs
# 6) Check that the pool size was expaned
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-06-12)
