| # DESCRIPTION: |
| # Ensure that the MMP thread is writing uberblocks. |
| # |
| # STRATEGY: |
| # 1. Set zfs_txg_timeout to large value |
| # 2. Create a zpool |
| # 3. Find the current "best" uberblock |
| # 4. Sleep for enough time for a potential uberblock update |
| # 5. Find the current "best" uberblock |
| # 6. If the uberblock never changed, fail |
