36# DESCRIPTION:
37# The secondary side of a zpool mirror can be zeroed without causing damage
38# to the data in the pool
39#
40# STRATEGY:
41# 1) Write several files to the ZFS filesystem in the mirrored pool
42# 2) dd from /dev/zero over the secondary side of the mirror
43# 3) verify that all the file contents are unchanged on the file system
