== Hard drive harness tool
-- Author: SÃ©bastien Pierre, XPrima Corp <sebastien@xprima.com> -- Version: 0.1.5

_Rugg_ is a hard drive and filesystem harness tool that allows you to test and benchmark drives and filesystems, by writing simple to complex scenarios that can mimic the behaviour of real-world applications.

What makes Rugg special is that it can be easily customized to test specific usages of the filesystem. Initially, Rugg was made to test new database server harddrives inteded to host a Postgres database.

Here how you ''check that 100 threads can fill up a 100Gb zone of your hard drive without data corruption'':

> zone 100Gb, subdivide100 | fill same binary, ensure same

Features

_Rugg_ offers a number of unique features, which make it a flexible tool to help you reproduce particular condition that you would like to exercise:

You write scenarios using a simple shell-like language
You can easily express parallel and sequential processes
Many operations are already provided, including data generation
Can be easily extend thanks to its Python implementation

Thanks to its features, Rugg can be used as a versatile, easy disk and filesystem harness test, that can ensure that your hardware and software meets your application expectations.

Requirements

[Python](http://www.python.org) 2.4+
A UNIX platform (Rugg will probably not work under Windows)
The 'locate' utility, to easily find eligible data
Free space to make your tests

If you want to know more, you can have a look at the [Rugg guide](guide.html), which will tell you how to use Rugg in detail.
