Re: Universal drive adapter -

This is a posibility here with older releases (although F12 doesn't do this (thank you! thank you!); it now includes the hostname in the VG names created by anaconda during autopartitioning).

If that's the case then the easiest way to deal with it is to use the vgimportclone script distributed with recent versions of LVM2.

'mount' an LVM from one computer on another computer and they have the
same name, it's an issue. You probably have to rename the Group and
maybe the Volume so that it is distinctively different from what is
already mounted to avoid confusion before you can mount the second hard
drive LVM partitions.

New name & new UUID, although the script I mentioned will do all of this automatically.

With all that said, I don't think that's the case here as the pvdisplay that Bob posted would have complained like this if that were true:

And would also have reported more than one PV.
