I have been trying to figure out how glusterfs-fuse client will handle it when 1 of 3 bricks in a 3-way replica is slower than the others.
It looks like a glusterfs-fuse client will send requests to all 3 bricks when accessing a file. But what happens when one of the bricks is not responding in time?
We saw an issue when we added external load to the raid volume where the brick was located. The disk became 100% busy, and as a result the glusterfs-clients hang when they access the volume.
Is there a way to avoid this, and make the clients ask the other two bricks for the data when one brick is too slow?
Thanks
