If I have 5 clients, two of which are running an app which requires fcntl style file locking, do I need to mount lustre with -o flock on all five clients, or just the two that are using fcntl? What are the implications (if any) of mounting a lustre filesystem with -o flock? Thanks! Jay -------------- next part -------------- An HTML attachment was scrubbed...
