Oops, this was a Py3 v. Py2 issue -- Python3 saw the '%.2f' in the function that pretty-printed cache sizes and would fp-divide the two integers, whereas Pyhon2 saw that we were trying to divide two integers and used integer division. Fixed in the Gist. Kent: Any chance you'd like to pick up bcache-status into bcache-tools.git?
