10 dm-clone is a device mapper target which produces a one-to-one copy of an
11 existing, read-only source device into a writable destination device: It
12 presents a virtual block device which makes all data appear immediately, and
15 The main use case of dm-clone is to clone a potentially remote, high-latency,
16 read-only, archival-type block device into a writable, fast, primary-type device
17 for fast, low-latency I/O. The cloned device is visible/mountable immediately
