LVM2 | Shrink Volume Group

Hi.
I would like to shrink the vg0 Volume Group to 500GB and add a new one "vg_vm_images" of size 500GB also.
How to archive that?
Thanks.

Re: LVM2 | Shrink Volume Group

You have a volume group (vg0) containing one physical volume (sda3) sized nearly 11 TB.

AFAIK creating multiple volume groups with only one PV is not possible.
