# DESCRIPTION:
# Create dRAID pool using the maximum number of vdevs (255). Then verify
# that creating a pool with 256 fails as expected.
#
# STRATEGY:
# 1) Verify a pool with fewer than the required vdevs fails.
# 2) Verify pools with a valid number of vdevs succeed.
# 3) Verify a pool which exceeds the maximum number of vdevs fails.
