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. For each checksum:
41# 2.	Create a file using the checksum
42# 3.	Corrupt all level 1 blocks in the file
43# 4.	Export and import the pool
44# 5.	Verify that there are checksum errors
