I’d like to change some of the settings for my RAID 5 HD, like the max sectors per IO. I know how to do this at the terminal, by entering:
echo “64” > /sys/block/sda/queue/max_sectors_kb
My question is this though. Each time I reboot this settings get reset. Can I add these commands to my sysctl.conf file so they run each time openSUSE starts up?
what about commands to set the Read Ahead Cache like
blockdev --setra 16384 /dev/sdb?
Can that also just be placed in the sysctl.conf.
If the answer is no, can anybody instruct me on how to do this?
