lvm2 partition size *IS* 72M

DF reports amount of space in your filesystem - which will be always smaller 
then the actual size of partition itself.

I.e. try to do exact same steps with i.e. GPT partition size - you will get 
very much same results.

So simply said:

lvm2 partitions size >> size of filesystem user usable size
