missing partition size

[irulvam]

I need the partition size status to know the current capacity, so that my client can see if the disk is running out and can contact me to increase the disk

<?php echo lng('PartitionSize').': <span class="badge text-bg-light border-radius-0">'.fm_get_filesize(@disk_free_space($path)) .'</span> '.lng('FreeOf').' <span class="badge text-bg-light border-radius-0">'.fm_get_filesize(@disk_total_space($path)).'</span>'; ?>

Can you make an option to display the partition size?
