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