+# DESCRIPTION:
+#	'zpool attach poolname raidz ...' should fail if raidz_expansion
+#	feature is not enabled.
+#
+# STRATEGY:
+#	1. Create raidz pool with raidz_expansion feature disabled
+#	2. Attempt to attach a device to the raidz vdev
+#	3. Verify that device attached failed
+#	4. Destroy the raidz pool
