Title:
  [Lucid] LVM Auto partitioning fails if LVM metadata exists on disks
  where partitions get created.

Status in “partman-auto-lvm” package in Ubuntu:
  New

Bug description:
  Binary package hint: partman-auto-lvm

  I see references to this problem in other bugs, but it appears to be
  believed to be fixed.  Perhaps this is a regression.  To reproduce:

  1.  Begin a lucid install with LVM auto partitioning.  Let the partitioning step finish.
  2.  Delete the partition table
  3.  Start another lucid install and select LVM auto partitioning.

  You get an error that the volume group name is already in use.  If you
  continue and try again, then it works.  My understanding is that even
  if you preseed every option available to remove existing LVM data, if
  LVM data suddenly appears when the disk gets partitioned, partman is
  incapable of removing it.  If you select continue, it restarts the
  partitioning step and allow the removal of the existing data since the
  partitions now exist.

  We need a way to preseed something that says "no really, erase the
  disk."

  I will test if this is a problem in older releases or if it is new in
  Lucid.
