You don't need to take the filesystem offline for lfsck. Also, I have rewritten large parts of lfsck and also fixed the parallelization code. I need to review all patches again and probably also make a hg or git repository out of it. Unfortunately, I always have more tasks to do than I manage to do... But given the fact that I fixed several bugs and added safety checks, I think my version actually is better than upstream. Let me know if you are interested and I can put a tar ball of e2fsprogs-sun-ddn on my home page.
