Description of problem: Note:this is a cosmentic bug and no functionality is impacted, hence raising as low severity when brick mux is enabled and user sets some value to cluster.max-bricks-per-process, say 20 and later disables brick mux, then we must be reseting the value of cluster.max-bricks-per-process to 1( not even 0, as 1 makes more sense) However, we still keep the value as 20 with brick mux now disabled Version-Release number of selected component (if applicable): -====================== 3.8.4-35 How reproducible: Steps to Reproduce: 1.enable brick mux and set cluster.max-bricks-per-process to 20 2. now disable brick mux Actual results: =============== brick mux disablement must set cluster.max-bricks-per-process to 1 or 0
