Hello all, Running a box with 2x1TB software raid disks. A while back I read up about disk write caching and it's pros/cons.
I then decided to disable it on my box. Edited /etc/conf.d/hdparm and added -W0 for sata_all_args. And added it to the default runlevel. It works, on bootup it turns off write caching. But a while later when KDE is up and running and I check with hdparm -W /dev/sd? write caching is on again. Now, I have two questions, How can I find out what turned it back on, and how can I prevent it? Is it necessary/prudent to turn it off in the first place? At the moment I run a cron job that checks every 10 minutes and turns it off if it is enabled. But that feels like a somewhat ugly solution... Kind regards, Coert Waagmeester
