Hi Tejun,
Sorry, this is a really really slow reply. This email came at an
unusually busy time and I did not reply before it got buried in the
deluge.
2. This is from Roland. Make smartd aware of the problem and warn user
if load/unload count per powered on hours goes too high. Maybe the
warning can direct the user to linux-ata.org page?
It would be easy to implement this in smartd. But I'm concerned about
three things:
-- most people don't run smartd (I think by default it is off on
the main Linux distros). Those wise enough to run smartd will
probably be aware of the issue, since it's gotten lots of buzz. And
even if smartd is turned on in the distro it is normally not
configured to send warning emails.
-- I'm not sure if the attribute used for head load/unload is a standard
one. On my current laptop Hitachi disk it is attribute 193. Does
anyone know if this is standard?
-- I'm not sure at what threshold to send warning emails. If we send
too many false alarms, they will be ignored by users.
Let me know if you have suggestions or comments about these points.
Cheers,
Bruce
