- #
- # 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
- #
- # TESTABILITY: explicit
- #
- # TEST_AUTOMATION_LEVEL: automated
- #
- # CODING_STATUS: COMPLETED (2005-08-10)
