- # ID: reservation_004_pos
- #
- # DESCRIPTION:
- #
- # When a dataset which has a reservation set on it is destroyed,
- # the space consumed or reserved by that dataset should be released
- # back into the pool.
- #
- # STRATEGY:
- # 1) Create a filesystem, regular and sparse volume
- # 2) Get the space used and available in the pool
- # 3) Set a reservation on the filesystem less than the space available.
- # 4) Verify that the 'reservation' property for the filesystem has
- # the correct value.
- # 5) Destroy the filesystem without resetting the reservation value.
- # 6) Verify that the space used and available totals for the pool have
- # changed by the expected amounts (within tolerances).
- # 7) Repeat steps 3-6 for a regular volume and sparse volume
- #
- # TESTABILITY: explicit
- #
- # TEST_AUTOMATION_LEVEL: automated
- #
- # CODING_STATUS: COMPLETED (2005-07-19)
