Who sets this value? Is this from pm-utils or what? Is this only openSUSE or any distro out there. If not, how the other distros fixed this?
This has nothing to do with pm-utils. The manufacturer sets this value upon making the drive. I have found nothing about this being fixed in other distros apart from this ubuntu bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/607560 it says that journal had been written too often and that it's been fixed in kernel 2.6.something. Guide to increase the head parking timeout for WD drives: http://www.storagereview.com/how_to_stop_excessive_load_cycles_on_the_wester... (Requires a dos tool provided by WD, wdidle. Hdparm does the same but its manpage says it's beter to use the dos tool.) Btw maybe someone from SUSE could talk to WD and hdparm upstream guy and arrange that WD helps with making this tweak possible in linux too? But this happened on some laptops too, manufacturers tend to produce HDDs with aggressive head parking times, WD Caviar Green is not the only one. Ideas for possible solutions: 1. write an ugly hack-script (probably a systemd unit?) that reads HDD head parking time and sets it to something reasonable if it's too short. Has to be run during boot and probably resume? Seems like something we should avoid. 2. Fix all the stuff that accesses the disk unnecessarily or too often, like journal, syslog, etc. I don't know if this is possible at all? Please assign it to someone else. All I do is maintain hdparm and there is nothing more I can do apart from gathering this information and throwing in some ideas, thanks. -- 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.
