I'm calculating overprovisioning ratio by dividing total_commited by size_total
aggr['overprovisioning']=aggr['total_committed']*100//aggr['size_total']
This seems to be valid for our FAS clusters but it's showing too low values for AFF clusters.
How is the calculation of "total_commited" done? Do I need to take into account also volume_compression_space_savings and volume_dedupe_space_savings in order to calculate proper overprovisioning level ?
BTW Is it normal that after every single volume/lun creation I'm not getting value of total_committed for that particulat aggregate for good ~30 minutes ?
