+# DESCRIPTION:
+# 	Negative for FreeBSD Only
+#
+#	Attempting to expand a RAIDZ should fail if the scratch area on the
+#	existing disks contains BTX Server binary (used to boot FreeBSD when
+#	using MBR partitions with ZFS).
+#
+# STRATEGY:
+#	1. Create raidz pool
+#	2. Add a BTX header to the reserved boot area
+#	3. Attempt to attach a device to the raidz vdev
+#	4. Verify that device attached failed
+#	5. Destroy the raidz pool
