Volker, I'm interested in both the readahead and scheduler settings. I played with this a bit when testing my RAID6 but never got around to making anything permanent as I had a couple of questions: 1) Is there some standard place to put my desired settings within the Gentoo configuration framework or do I have to write my own scripts, etc.? 2) As the machine is RAID6 do I need to do this explicitly for all 5 drives (sd[a,b,c,d,e]) or can I do it for the RAID /dev/md3? Thanks, Mark
