Sorry Marc. After offline communication with Qu, both
of us think the filesystem is hard to repair.
The filesystem is too large to debug step by step.
Every time check and debug spent is too expensive.
And it already costs serveral days.
Sadly, I am afarid that you have to recreate filesystem
and reback up your data. :(
Sorry again and thanks for you reports and patient.
