Maybe I was too verbose, so I'll rephrase more briefly: My tests indicate that fsync() on a DRBD device is returning before data has been written to non-volatile storage. This is unacceptable for any application that makes ACID guarantees. Is this something that should be working? Is there something I must do to enable the behavior I desire from fsync()?
