[Gluster-devel] FOP ratelimit?

[Emmanuel Dreyfus]

Hi

Yesterday I experienced the problem of a single user bringing down 
a glusterfs cluster to its knees because of a high amount of rename
operations.

I understand rename on DHT can be very costly because data really have
to be moved from a brick to another one just for a file name change.
Is there a workaround for this behavior?

And more generally, do we have a way to ratelimit FOPs per client, so
that one client cannot make the cluster unusable for the others?
