A.1.1. The linear Mapping Target

A linear mapping target maps a continuous range of blocks onto another block device. The format of a linear target is as follows:

start length linear device offset

start: starting block in virtual device
length: length of this segment
device: block device, referenced by the device name in the filesystem or by the major and minor numbers in the format major:minor
offset: starting offset of the mapping on the device

The following example shows a linear target with a starting block in the virtual device of 0, a segment length of 1638400, a major:minor number pair of 8:2, and a starting offset for the device of 41146992.

0 16384000 linear 8:2 41156992

The following example shows a linear target with the device parameter specified as the device /dev/hda.

0 20971520 linear /dev/hda 384
