On the raw disk, you can do that with size=1tb io_limiut=1gb and add loops=x for however many iterations you want. If you mean from a file system, then you would need a 1TB file to achieve (roughly) the same thing. Not sure what you mean here, but are you referring to multiple 1GB files? -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
