Actually make a volume go missing? The easiest way to do that would be USB volumes (thumb drives), and just yank the drive out. Even if you don't want to physically pull the drive, I think you can tell a USB device to power down via a sysfs attribute, so that might be sufficient.

Thanks both, I'd thought about a USB drive, but didn't have one to hand at the time that I didn't mind messing up. The sysfs route sounds a bit safer though, and I can probably find one I don't need any more.
