Basically what I want is "the file which is used under CIFS share should not get overwritten from a nfs share and vice versa." . I might be looking for mandatory file locking in nfs share. > That may be tricky. Mandatory locking under unix is rather rare. Most unix apps use advisory locking. Windows however uses mandatory locking pretty much exclusively. The semantics of windows locks are quite different -- they don't necessarily map 1:1, particularly when you get into how overlapping byte ranges are handled and such. The best advice I can offer is to understand how your apps use locking and to do some testing to simulate those use cases. That should help outline where the differences are. Again, the samba lists are probably a better forum for this discussion. The developers that lurk on those lists generally have a good understanding of the subtleties involved in mapping file locks between the two platforms. With more specific questions you may be able to get more helpful answers as well. -- Jeff Layton <jlayton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
