linux - What Process is using all of my disk IO -

If I use "top" then I can see what the CPU is busy and in which process all my CPU Is used.

If I use "iostat -x" then I can see what drives is busy.

But how can I see which throughput of all the drives is being used in that process?

You are searching for iotop (assuming you have the kernel> 2.6.20 and Python 2.5 have been found). If you do not do this, you are hooking up in the file system. I recommend the former.
