# DESCRIPTION:
# Once a pool has been exported, but one or more devices are
# overlapped with other exported pool, import should handle
# this kind of situation properly.
#
# STRATEGY:
# 1. Repeat 1-3, create two test pools upon device files separately.
# These two pools should have one or more devices are overlapped.
# using the various combinations.
# - Regular pool
# - Mirror
# - Raidz
# 2. Create necessary filesystem and test files.
# 3. Export the test pool.
# 4. Verify 'zpool import -d' with these two pools will have results
# as described:
# - Regular, report error while any number of devices failing.
# - Mirror could withstand (N-1) devices failing
# before data integrity is compromised
# - Raidz could withstand one devices failing
# before data integrity is compromised
