How to make elevator/schedule type persistent across boots (multipath)
358556Oct 29 2010 — edited Nov 1 2010Hello All,
Running OEL 5.5 x64. Have set up multipath no probs, but notice that I get far better performance when using NOOP instead of CFQ, which is the default. Rather than having to change this every time I boot, wondering if there is a way to have it persistent across boots?
The issue is that it seems it must be done at the block level. For example, echo noop > /sys/block/sda/queue/scheduler . The problem is that these block device paths change all the time. I saw something about doing it within grub.conf, but that did not work for me (http://lonesysadmin.net/2008/02/21/elevatornoop/)
Thanks in advance!
