On a normal block device you can change the i/o scheduler like this:

# cat /sys/block/hda/queue/scheduler
noop anticipatory deadline [cfq]
# echo anticipatory > /sys/block/hda/queue/scheduler
# cat /sys/block/hda/queue/scheduler
noop [anticipatory] deadline cfq

How can I control the setting for a NFS volume or do I just have to set it globally in the boot config with

elevator=noop

or similar?

No, this is not possible.
NFS is providing a network mount and is outside of the block-device scheduler settings.

    Will it be affected by the global io scheduler change though? I assume so since the kernel still manages io to NFS Jun 17, 2014 at 16:43
