Is there an easy way to instrument disk IO in -current so one can tell
who is writing what?
I just put a new disk into my laptop. Even though the new disk is
slightly lower power, it manages to put all that energy into acoustic
radiation. The disk-seeks are annoyingly loud.
I've already turned on "noatime, nodevmtime, softdeps" and I still get
a some disk io every few minutes. I'm not running whois or anything
inherently noisy like that, but I do have cron, syslog, ntpd, amd,
Xdm. How do I find the villian short of exhaustive search by killing
one daemon at a time?
