From the article:
“If you reduce the Fractional Reservation to 0, you need to make sure the rate of change is within the volume
size, or you need to make sure the volume can auto-grow when required or even snap auto-delete to reduce
the reserved blocks and free up space (although I am not a huge fan of snap auto-delete for various reasons).”
