# 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
