Daniel,

Thanks for fast reply. But I looks like lvextend appends space after LV.

And after running lvextend we will get following:

[25GB LV] + [20 GB free space]

free space added after original LV.

But we need to prepend free space before original LV:

[20 GB free space] + [25GB LV]

free space added before original LV.

Thanks,
Alex
