A.1.1. The linear Mapping Target

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

starting block in virtual device


length of this segment


block device, referenced by the device name in the filesystem or by the major and minor numbers in the format major:minor


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
