rhn_check -vvv output illustrating the problem
This issue still affects koan-2.0.7-11.el6sat.noarch : The line 1458 (args = "LANG=C vgs...) will crash because of invalid literal for float(): 62.50g and therefor the "#remove gigabytes" is never executed. Adding --noprefix to the line 1458 will solve this.
