  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 #
