I have a problem that for the file data I need the fs MetaData is corrupted.
I hope that because I am using same pre allocate logic all over my FS then I can get the Maping from other clear state FS file
And read the data directly from the corrupted FS.
Is that making sense?

What you are doing wrong is that you aren't using the debugfs "dump"
command, which will do what you are trying to do.
