> 1) Non-ozone usages crosses *Reserved space*
>  * Need have warn audit log
>  * Need update metrics which can be used for reporting
>  
> This needs to be raised considering ozone container meta-data may occupy certain space as change in solution “1”. We might consider 5GB as an overlapping threshold to avoid raising audit / metrics.
>  
> This will be a new configuration:
> hdds.datanode.dir.du.reserved.overlap: 5GB
>  
> 20 Ozone available space < minSpaceToSpare
>  * Need have error audit log
>  * Metric to indicate
>  
> 3) ozone available space < (committed space + minFreeSpace)
>  * Need have warn log and metrics
>  * Need take more rigorous check when write data
