SubjectKeeping track of spin-down/spin-up and causes of spin-up?
Date
I clearly remember seeing a reference to some system that allowed to
keep track of causes of disk spin-up, but Google seems to say
I'm deluded. [ Or maybe my memory confused it for the facility used by
powertop to keep track of causes of CPU wake-ups? ]

In any case, I have a machine here whose disk keeps spinning back up
on a regular basis, and I can't seem to find any correlated event.
Is there a tool that can help me track down the reason why the disk
is accessed?


Stefan
