30# DESCRIPTION:
31# 	Negative for FreeBSD Only
32#
33#	Attempting to expand a RAIDZ should fail if the scratch area on the
34#	existing disks contains BTX Server binary (used to boot FreeBSD when
35#	using MBR partitions with ZFS).
36#
37# STRATEGY:
38#	1. Create raidz pool
39#	2. Add a BTX header to the reserved boot area
40#	3. Attempt to attach a device to the raidz vdev
41#	4. Verify that device attached failed
42#	5. Destroy the raidz pool
