Hisk disk io ?

Sorry for the repost, I posted in the wrong forum...

The question I am pondering over is ..

Anyone know how I find out which process is causing the most disk io ?

for what its worth : iotop needs kernel >= 2.6.20 http://guichaz.free.fr/misc/

any alternatives ?

Edit: Posted a link to the right forum, didn't notice you'd already posted it there too.

Huh ? I don't get :\

I just posted this here and in HTML questions by mistake

Anyway I'm trying to hunt down the issue by using sar its not pretty... linuxquestions seem to not have anything that I dont know already without the need to change my kernel...

have a read of the vmstat man pages, particularly for options -d -D and -p.

Process stats doooooood not global.

The closest I've got is by using :

sar -b -r -x ALL -d 1 1

but can't see the process that is causing the disk io...

but in fairness I got the feeling that it might be a process that forks and dies too rapidly for it to be noticed.
