Hi, using GlusterFS 6.7 with a 2+1 replicated volume, how are read requests load balanced, if at all? The reason I ask is that we see consistently higher usage/load on the first brick when compared to the second data brick. Are there any parameters to influence the read balancing?

I know about 'cluster.choose-local: off' which controls if FUSE process
on a Gluster Server should query only local brick or all bricks.In my case,
I'm using oVirt on a Hyperconverged setup.

Hi,
using GlusterFS 6.7 with a 2+1 replicated volume, how are read requests load
balanced, if at all?
The reason I ask is that we see consistently higher usage/load on the first
brick when compared to the second data brick.
Are there any parameters to influence the read balancing?
Thanks,
Stefan
