I have CentOS 6.x Linux server with kernel 2.6.32-573.8.1.el6.x86_64
.
I did some checks today and I found that disk elevator is "deadline".
[root@srv ~]# cat /sys/block/sda/queue/scheduler
noop anticipatory [deadline] cfq
I have almost same server, but installed 4 mo ago. it is with kernel 2.6.32-573.3.1.el6.x86_64
. It's scheduler is "cfq" as expected.
Is there some changes in the kernel, or just my hosting company did it?
I also can not find where this is set - /etc/sysctl.conf
is stock.
