Add a 4 files that are to be truncated later 30# 3. Take a snapshot of the filesystem 31# 4. Truncate one of the files from 32M to 128k 32# 5. Truncate one of the files from 512k to 384k 33# 6. Truncate one of the files from 512k to 0 to 384k via reallocation 34# 7. Truncate one of the files from 1k to 0 to 512b via reallocation 35# 8. Take another snapshot of the filesystem 36# 9. Send and receive both snapshots 37# 10.
