Описание (Description)

dmsetup manages logical devices that use the device-mapper driver. Devices are created by loading a table that specifies a target for each sector (512 bytes) in the logical device.

The first argument to dmsetup is a command. The second argument is the logical device name or uuid.

Invoking the dmsetup tool as devmap_name (which is not normally distributed and is supported only for historical reasons) is equivalent to dmsetup info -c --noheadings -j major -m minor.
