Yup. Maybe I don't understand exactly what this does, but if the
drives are idle (i.e. no reads or writes) for say an hour or more,
why would there be any dirty data to flush?
That's why I'm confused---this machine literally goes for hours at a
time without and read or write attemps on these drives.
