Changing the deadline scheduler in RHEL 6
 

I've been asked to change the io scheduler to deadline. If I follow this example it sets it until I reboot. So, how do I make it permanent?


$ echo deadline > /sys/block/sda/queue/scheduler

Looks like you need to set elevator=deadline in the kernel options: RHEL5 IO tuning guide (PDF) https://www.google.co.uk/url?sa=t&rc...4io4cg&cad=rja
