LVM linear and striped mapping

[russo]

Hello Guys,

What is the main difference between linear mapping and striped mapping in LVMÉ
Thanks in advance.

I hope it would help.

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],

and so on. In certain situations this strategy can improve the performance of the logical volume.

I would recommend you to check.

It's an excellent tutorial.
