24 # Verify incremental receive properly handles reallocation.
27 # 1. Create a pool containing an encrypted filesystem.
28 # 2. Use 'zfs send -wp' to perform a raw send of the initial filesystem.
29 # 3. Repeat the following steps N times to verify raw incremental receives.
30 # a) Randomly change several key dataset properties.
31 # b) Modify the contents of the filesystem such that dnode reallocation
32 # is likely during the 'zfs receive', and receive_object() exercises
33 # as much of its functionality as possible.
34 # c) Create a new snapshot and generate an raw incremental stream.
35 # d) Receive the raw incremental stream and verify the received contents.
36 # e) Destroy the incremental stream and old snapshot.
