+# DESCRIPTION:
+# Verify 'zpool sync' can sync txgs to the pool(s) main vdevs.
+#
+# STRATEGY:
+# 1. Create a pool
+# 2. Use zdb to obtain current txg
+# 3. Create a file in the pool if we're not using force sync
+# 4. Use zpool sync to sync pool
+# 5. Verify the new txg is now bigger than the saved one
+#
