From: "Randall S. Becker" <rsbecker@xxxxxxxxxxxxx>
The corrupt_graph_and_verify method has been modified to use
truncate instead of the /dev/zero pseudo-device, which breaks on
platforms where the pseudo-device does not exist. truncate extends
files to a specified length filling with nulls, providing a similar
function to the use of dd in this case.
