31# DESCRIPTION:
32# Verify feature@head_errlog=disabled works.
33#
34# STRATEGY:
35# 1. Create a pool with feature@head_errlog=disabled and a file
36# 2. zinject checksum errors
37# 3. Read the file
38# 4. Take a snapshot and make a clone
39# 5. Verify that zpool status displays the old behaviour.
