The VG contains the same space in both cases so do the simplest ie the first option. In both cases you'll need to run lvcreate for 460G followed by lvextend for 1G.

Thanks for the response.
For some reason even the first option does not work.
I created 3 partitions, added the 2 same sized ones to a vg, created a striped lv, then extended the vg to include the third small partition. After this I tried extending the lv to the new partition, but got the error below. Could you, please tell me what I am doing wrong? TIA.
