What tool can tell me why my hard disk light is essentially on,

top doesn't seem to show the culprit since it mustn't use enough CPU.
Fedora 9 i386 if it matters.
Also, is there similar for network ?
Is there a tool which will allow me to track io by process? I can do it
by putting a printk in the kernel, rebuilding, and wading through MB of
logs, but what I want is a way to find out which process or kthread is
writing to my disk when the system is dead idle.
Of course the logging operation causes disk i/o... so it's kind of ugly
to use.
In the Old Days (tm) there used to be a utility called iostat, but it
seems to have joined the 'eavenly choir eternal.
No, it's around. "yum -y install sysstat" (at least for F8, dunno about
F9...haven't set it up yet).
