# DESCRIPTION:
# 'zfs load-key' should only load a key for an unloaded encrypted dataset.
#
# STRATEGY:
# 1. Attempt to load the default dataset's key
# 2. Unmount the dataset
# 3. Attempt to load the default dataset's key
# 4. Create an encrypted dataset
# 5. Unmount the dataset and unload its key
# 6. Attempt to load the dataset's key
# 7. Verify the dataset's key is loaded
# 8. Attempt to load the dataset's key again
# 9. Create an encrypted pool
# 10. Unmount the pool and unload its key
# 11. Attempt to load the pool's key
# 12. Verify the pool's key is loaded
# 13. Attempt to load the pool's key again
