+# DESCRIPTION:
+# Sanity test to make sure checksum algorithms work.
+# For each checksum, create a file in the pool using that checksum.  Verify
+# that there are no checksum errors.  Next, for each checksum, create a single
+# file in the pool using that checksum, corrupt the file, and verify that we
+# correctly catch the checksum errors.
+#
+# STRATEGY:
+# Test 1
+# 1. Create a mirrored pool
+# 2. Create a file using each checksum
+# 3. Export/import/scrub the pool
+# 4. Verify there's no checksum errors.
+# 5. Clear the pool
+#
+# Test 2
+# 6. For each checksum:
+# 7.	Create a file using the checksum
+# 8.	Corrupt all level 0 blocks in the file
+# 9.	Scrub the pool
+# 10.	Verify that there are checksum errors
