Locking with CTDB

[Henning Henkel]

Hi list,
at the moment I'm writing at my diploma thesis in the ctdb orbit. I got 
the impression that ctdb depends on the locking of the underlying 
filesystem and so I'm a little confused why there's the need for an 
extra ctdb and why this can't be done with multiple samba servers.

Maybe you can provide me some extra information on  the  matter of 
locking or on the general approach of developing ctdb.

Cheers
