31# DESCRIPTION:
32# Sanity test to make sure checksum algorithms work.
33# For each checksum, create a file in the pool using that checksum.  Verify
34# that there are no checksum errors.  Next, for each checksum, create a single
35# file in the pool using that checksum, corrupt the file, and verify that we
36# correctly catch the checksum errors.
37#
38# STRATEGY:
39# Test 1
40# 1. Create a mirrored pool
41# 2. Create a file using each checksum
42# 3. Export/import/scrub the pool
43# 4. Verify there's no checksum errors.
44# 5. Clear the pool
45#
46# Test 2
47# 6. For each checksum:
48# 7.	Create a file using the checksum
49# 8.	Corrupt all level 0 blocks in the file
50# 9.	Scrub the pool
51# 10.	Verify that there are checksum errors
