Oh perfect.
Thanks, i really didn't realize that fs_discontig was a flag.
The old tools didn't report it in the docs so i didn't find it anywhere.

Now: sorry to be so annoying but i have googled without success ( i only 
found the patch that adds the following error).

I cannot find nor the reason for this error:

tunefs.ocfs2: Chain allocator is corrupt while opening device "/dev/drbd2"

Nor the cause, anywhere.
fsck doesn't seems to find the problem.

Thanks again. I hope thise questions will help other people as well.
