    Description

      Currently for files within snapshots, the file diff only records block list (before the truncate feature we only recorded file length). Now the file diff should also be able to capture the block groups.

      In the meanwhile, if a file has been truncated in history and the change has been recorded in snapshots, when we convert the file to EC, the conversion should also cover the data that were truncated and the corresponding file diff needs to be updated accordingly.
