| # |
| # DESCRIPTION: |
| # 'zfs mount -O' allow the file system to be mounted over an existing |
| # mount point, making the underlying file system inaccessible. |
| # |
| # STRATEGY: |
| # 1. Create two filesystem fs & fs1, and create two test files for them. |
| # 2. Unmount fs1 and set mountpoint property is identical to fs. |
| # 3. Verify 'zfs mount -O' will make the underlying filesystem fs |
| # inaccessible. |
| # |
