38# DESCRIPTION:
39#   If a vdev experiences checksum errors, it will become degraded.
40#
41#
42# STRATEGY:
43#   1. Create a storage pool.  Only use the file vdevs because it is easy to
44#      generate checksum errors on them.
45#   2. Mostly fill the pool with data.
46#   3. Corrupt it by DDing to the underlying vdev
47#   4. Verify that the vdev becomes DEGRADED.
48#   5. ONLINE it and verify that it resilvers and joins the pool.
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING STATUS: COMPLETED (2012-08-09)
