[Bug 154086] Re: Installing to HDD with previous ubuntu fails to create fresh LVM claiming group already in use

[Dmitrijs Ledkovs]

Upon calling create Volume Group a few checks are done.
One of the check is Volume Group name collision.
This could be valid (duplicate name, pre-seed mistake, etc) or it could be a "zombie" Volume Group that got detected on otherwise empty partition.
There is a codepath to remove existing volume groups with confirmation.
I think instead claiming name collision, we should take that path:
- it can be pre-seeded out
- user can proceed to remove "zombie"/name-conflict or back out to partitioning

I will try to patch this & test it.

Does this sound reasonable?

Bug description:
  Binary package hint: debian-installer

  I have a ubuntu 7.10 beta server I'd like to reinstall from scratch.
  During the disk partitioning, I'd opted for "Guided - Use entire disk
  and setup LVM" Part way through it informed me that the volume group
  name was already in use. Surely this option should setup a new LVM
  instance and use the entire disk, even if a LVM instance already
  existed?

  How can I blank this without manually having to create volumes? I
  think this is a bug
