30# DESCRIPTION:
31#	'zpool attach poolname raidz ...' should attach new devive to the pool.
32#
33# STRATEGY:
34#	1. Create block device files for the test raidz pool
35#	2. For each parity value [1..3]
36#	    - create raidz pool with minimum block device files required
37#	    - for each free test block device
38#	        - attach to the pool
39#	        - verify the raidz pool
40#	    - destroy the raidz pool
