hi list, i am trying to change the input and output scheduler on my
disks, and it does not allow me ,
I have several virtualized vm over kvm, and when I try to make the
change it shows me this message:

echo "noop" > /sys/block/vda/queue/scheduler

-bash: echo: write error: Invalid argument

kernel version:

3.10.0-1127.13.1.el7.x86_64

any idea?
