- # ID: clone_001_pos
- #
- # DESCRIPTION:
- # Create a snapshot from regular filesystem, volume,
- # or filesystem upon volume, Build a clone file system
- # from the snapshot and verify new files can be written.
- #
- # STRATEGY:
- # 1. Create snapshot use 3 combination:
- # - Regular filesystem
- # - Regular volume
- # - Filesystem upon volume
- # 2. Clone a new file system from the snapshot
- # 3. Verify the cloned file system is writable
- #
- # TESTABILITY: explicit
- #
- # TEST_AUTOMATION_LEVEL: automated
- #
- # CODING_STATUS: COMPLETED (2005-08-25)
