 #
 # ID: zfsd_fault_001_pos
 #
 # DESCRIPTION: 
 #   If a vdev experiences IO errors, it will become faulted.
 #       
 #
 # STRATEGY:
 #   1. Create a storage pool.  Use gnop vdevs so we can inject I/O errors.
 #   2. Inject IO errors while doing IO to the pool.
 #   3. Verify that the vdev becomes FAULTED.
 #   4. ONLINE it and verify that it resilvers and joins the pool.
 #
 # TESTABILITY: explicit
 #
 # TEST_AUTOMATION_LEVEL: automated
 #
 # CODING STATUS: COMPLETED (2012-08-09)
