Does anyone have suggestions for easily simulating a missing volume in LVM on bare metal?
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.
