The administrator can choose between a couple of general strategies for mapping logical extents onto physical extents:
Linear mapping will assign a range of PE's to an area of an LV in order eg., LE 1 - 99 map to PV1 and LE 100 - 347 map onto PV2.
Striped mapping will interleave the chunks of the logical extents across a number of physical volumes eg.,
1st chunk of LE[1] -> PV1[1], 2nd chunk of LE[1] -> PV2[1], 3rd chunk of LE[1] -> PV3[1], 4th chunk of LE[1] -> PV1[2], |
