# Description:
# Receiving a snapshot with large blocks and raw sending it succeeds.
#
# Strategy:
# 1) Create a set of files each containing some file data in an
#	encrypted filesystem with recordsize=1m.
# 2) Snapshot and send with large_blocks enabled to a new filesystem.
# 3) Raw send to a file. If the large_blocks feature is not activated
#	in the filesystem created in (2) the raw send will fail.
