??? is to lsof as top is to ps: what is ???
Something is accessing my harddisk every few seconds, even when I'm just staring at an empty xfce desktop. I've always had that, but now I have a noisier disk it has become a little more annoying.
I've made /tmp a tmpfs (ramdisk), and made /var/tmp a symlink to that /tmp, set noatime on / and /home, I have plenty free memory, and STILL it makes noise every few seconds. If only I knew what process was doing that...
So, does anyone know a tool that can show me what is accessing the disk at any moment, similar to how top can be used to see what process is using the cpu? Or does anyone have any other ideas for preventing use of the disk (except doing everything in ramdisk and other methods that have a high risk of data loss)?
