# DESCRIPTION:
# Verify that zvols with dedup=on and encryption=on can be sent and received
# with a deduplicated raw send stream.
#
# STRATEGY:
# 1. Create a zvol with dedup and encryption on and put a filesystem on it
# 2. Copy a file into the zvol a few times and take a snapshot
# 3. Repeat step 2 a few times to create more snapshots
# 4. Send all snapshots in a recursive, raw, deduplicated send stream
# 5. Mount the received zvol and verify that all of the data there is correct
#
