39# DESCRIPTION:
40# The primary side of a zpool mirror can be mangled causing without damage
41# to the data in the pool
42#
43# STRATEGY:
44# 1) Write several files to the ZFS filesystem mirror
45# 2) dd from /dev/urandom over the primary side of the mirror
46# 3) verify that all the file contents are unchanged on the file system
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2005-10-20)
