Is it possible to configure the Linux kernel I/O scheduler for an NFS mount?

  • 772

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?

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