[linux-lvm] same LV UUID after vgmerge

[Magni Fabrizio]

Hi Alasdair,

the lvm version is:

# lvm version
  LVM version:     2.00.15 (2004-04-19)
  Library version: 1.00.19-ioctl (2004-07-03)
  Driver version:  4.3.0

and I converted my VG with vgconvert.

Now I restored all my original volume group and I'm ready for another
test.

Is it safe to edit the UUID by hand?

Fabrizio
