  24 # DESCRIPTION:
  25 # Verify that zvols with dedup=on and encryption=on can be sent and received
  26 # with a deduplicated raw send stream.
  27 #
  28 # STRATEGY:
  29 # 1. Create a zvol with dedup and encryption on and put a filesystem on it
  30 # 2. Copy a file into the zvol a few times and take a snapshot
  31 # 3. Repeat step 2 a few times to create more snapshots
  32 # 4. Send all snapshots in a recursive, raw, deduplicated send stream
  33 # 5. Mount the received zvol and verify that all of the data there is correct
  34 #
