Overview
Device Mapper is a kernel-based framework for volume management. It maps physical block devices onto higher level virtual block devices. Device mapper also offers file system snapshots and thin provisioning. The device mapper framework is the foundation of logical volume manager (LVM), software RAIDs, dm-crypt disk encryption and Docker device-mapper storage backend
