Hello list
On my server almost half of files are duplicated, and there are almost
100GB of data which is growing fast. I'm using weekly script to find
duplicated files and replace them with hardlinks. Everything is fine as
long as users aren't trying to edit and save some documents which have
hardlinks. With samba 3.3 it seems that hardlinks aren't unlinked before
file is saved.
Is there any way to force samba to unlink file before write?

Wouldn't that be a function of the application program?
Some applications do similar to that -- like a rename & create (where the
old file will be around as a backup). But some applications may try
to modify the file in-place. It depends on the application.
You might be able to force the issue by changing the
permissions/ownership on the linux server to a '3rd party' login and
set other permissions to read-only. Then anyone who wants to write
would have to delete the copy that is there (or rename it).
