If I'm reading what you are writing right, then you need to read up a  
bit on how the file systems work.  :-)

If you have two servers file system drivers use the same physical  
storage then you need block level[1] locking (not "file level" locking).

You should subscribe to another list that's more relevant[2] and then  
take a few steps back and figure out what you need and then get help  
to find the best solution.  You are asking "How can I get X to do Y"  
when you really want to ask "How do I do Z".

  - ask

[1] to simplify it a bit.
[2] the scalable list maybe, scalable-subscribe at arctic.org.
