> 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
