No, see chattr man page: S = synchronous updates. It doesn't say anything about not using the buffer cache. You need to use O_DIRECT for that. > Is it same raw devices and if not, what is different ? Totally unrelated. It means that each I/O is waited on by the kernel before it returns to user space.
