# ID: zfsd_degrade_001_pos
#
# DESCRIPTION: 
#   If a vdev experiences checksum errors, it will become degraded.
#       
#
# STRATEGY:
#   1. Create a storage pool.  Only use the file vdevs because it is easy to
#      generate checksum errors on them.
#   2. Mostly fill the pool with data.
#   3. Corrupt it by DDing to the underlying vdev
#   4. Verify that the vdev becomes DEGRADED.
#   5. ONLINE it and verify that it resilvers and joins the pool.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2012-08-09)
