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