> Currently, (scmUsed / capacity) is used to calculate the disk utilization. When reserved space for non-ozone usage is defined,  scmUsed cannot reflect the data used by non-ozone usage, while free space can. 
> So change to use formula ( capacity - free ) / capacity.  This is also consist with the formula used by Container balancer.
