- # DESCRIPTION:
- # Verify that zfs unmount and destroy in a snapshot directory will not cause error.
- #
- # STRATEGY:
- # 1. Create a file in a zfs filesystem, snapshot it and change directory to snapshot directory
- # 2. Verify that 'zfs unmount -a' will fail and 'zfs unmount -fa' will succeed
- # 3. Verify 'ls' and 'cd /' will succeed
- # 4. 'zfs mount -a' and change directory to snapshot directory again
- # 5. Verify that zfs destroy snapshot will succeed
- # 6. Verify 'ls' and 'cd /' will succeed
- # 7. Create zfs filesystem, create a file, snapshot it and change to snapshot directory
- # 8. Verify that zpool destroy the pool will succeed
- # 9. Verify 'ls' 'cd /' 'zpool list' and etc will succeed
