22 | # DESCRIPTION: | |
23 | # Verify 'zpool sync' can sync txgs to the pool(s) main vdevs. | |
24 | # | |
25 | # STRATEGY: | |
26 | # 1. Create a pool | |
27 | # 2. Use zdb to obtain current txg | |
28 | # 3. Create a file in the pool if we're not using force sync | |
29 | # 4. Use zpool sync to sync pool | |
30 | # 5. Verify the new txg is now bigger than the saved one | |
31 | # | |
