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.
