https://bugzilla.novell.com/show_bug.cgi?id=338230 Summary: frequent hard disk load/unload cycles on laptop Product: openSUSE 10.2 Version: Final Platform: x86-64 OS/Version: openSUSE 10.2 Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mszeredi@novell.com QAContact: qa@suse.de Found By: --- On ThinkPad-T60 with Hitachi (HTS541080G9SA00) drive I see freqent load/unload cycles: 'smartctl -A' reports: Power_On_Hours: 2187 Load_Cycle_Count: 382333 This is about 3 cycles per minute, which is unacceptably high. If I manually set the power management of the drive with hdparm -B 254 /dev/sda the problem goes away, but the power management is reset to 128 after a resume from ram. This is an old problem, but recently got lots of publicity: https://launchpad.net/bug59695.html However the workarounds suggested for Ubuntu don't apply to SUSE, since we seem to have a different way of handling power management events. What is the suggested workaround for SUSE? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=338230#c3 David Bailey changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dbailey@datanetworks.com --- Comment #3 from David Bailey 2007-11-26 06:46:07 MST --- I'm seeing similar behavior of openSUSE 10.3 x86-64 on a Dell Precision M90. With the default configuration, I'm seeing a Load_Cycle_Count / Power_On_Hours ratio of 30.8216 or nearly 31 load/unloads per minute. This laptop is usually used with the power adapter plugged in. This means that the Seagate ST9160823AS drive according to the manufacturer specifications of somewhere around 600,000 load/unload cycles per drive lifetime, I can expect only 2.2 years of operational use of the drive. As this laptop is often on 24 hours per day, this is unacceptable. Because servers and desktops are implementing power management as well, this is going to impact all kinds of systems. I imagine this is related to Linux swap behavior impacting the power management features of the drive. Since this laptop has 3,354,360 bytes of usable memory, perhaps we should look into increasing the "cost" of swapping pages out to disk on systems that are performing power management on their drives? Another thought would be to pre-cache the important libraries and keep them from getting flushed during normal use? Another more radical option would be to disable swap unless memory becomes critically low, but I've found that disabling swap can impact system stability in certain cases. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

We're working on that for the next openSUSE release. Some kind of real fix, or a good workaround, would be to place a new hook into /etc/pm/power.d/ (some hints of doing this are at http://en.opensuse.org/Pm-utils#Creating_your_own_hooks) It basically looks like this: ============================= #!/bin/bash /usr/lib/pm-utils/functions case "$1" in true) echo "**disabled pm harddisk" <some hdparm command> ;; false) echo "**enabled pm for harddisk" <some hdparm command> ;; esac ============================ This can be called with 'pm-powersave {true,false}' and is also called by kpowersave or gnome-power-manager. Maybe we should create a openSUSE wiki page with a suitable hook.

I disabled the spindown with CONTROL_HD_IDLE_TIMEOUT=0 since a APM value of < 128 will spin down my disk no matter what idle timeout is given.

Yes, same here. I disabled it in my old 10.3 script, too. It was derived from http://en.opensuse.org/Disk_Power_Management However, there seem to be a problem with some proc values: # pm-powersave true [...] Adjusting 2.6 kernel parameters to enable laptop mode.
