#
# DESCRIPTION:
# Verify error scrub clears the errorlog, if errors no longer exist.
#
# STRATEGY:
# 1. Create a pool and create file in it.
# 2. Zinject errors and read using dd to log errors to disk.
# 3. Make sure file name is mentioned in the list of error files.
# 4. Start error scrub and wait for it finish.
# 5. Check scrub ran and errors are still reported.
# 6. Clear corruption and error scrub again.
# 7. Check scrub ran and errors are cleared.
