Hello ! I am trying to spot the application which are regularly using the disk, waking it up from sleep and eating unnecessary my battery. Is there some program which could log (on a tmpfs of course ! ;-) ) any disk access with timestamp, file (well if it doesn't work at filesystem level, that doesn't hurt) and PID of the application for every disk access ?
Moreover, the Battery Powered Linux HOWTO is quite old, is there some other documents about all this. For example, how to instruct Linux to keep the data in cache longer ? -- BOFH excuse #150: Arcserve crashed the server again.
