Storage tests can involve hard-to-reproduce scenarios involving a complex sequence of events, often complicated by the differing behavior characteristics of different types of block devices. Linux has various block device testing devices: scsi_debug, dm-flakey, dm-delay, and so on. But what if the test requires a scenario not covered by the existing test devices? See examples of test devices created to simulate the behavior of real-world storage devices, in complex support cases, during the development of Virtual Data Optimizer (now in RHEL 7.5).
