# DESCRIPTION:
# Test the scrub after resilver zedlet
#
# STRATEGY:
# 1. Create a mirrored pool
# 2. Fault a disk
# 3. Replace the disk, starting a resilver
# 4. Verify that a scrub happens after the resilver finishes
#

# Backup our zed.rc

# Enable ZED_SCRUB_AFTER_RESILVER in zed.rc

# Wait for the resilver to finish, and then the subsequent scrub to finish.
