# DESCRIPTION:
# 'zpool import' should import a pool with Errata #3 while preventing
# the user from performing read write operations
#
# STRATEGY:
# 1. Import a pre-packaged pool with Errata #3
# 2. Attempt to write to the effected datasets
# 3. Attempt to read from the effected datasets
# 4. Attempt to perform a raw send of the effected datasets
# 5. Perform a regular send of the datasets under a new encryption root
# 6. Verify the new datasets can be read from and written to
# 7. Destroy the old effected datasets
# 8. Reimport the pool and verify that the errata is no longer present
#
