But not in this case. If both volumes are made by Anaconda and both have name "vg_alan-fedora" (as hostname) it may cause misunderstanding, for pvscanning, but as far as i know, pvs shows all VG even with same labels. Do you use Gnome? You check it with palimpsest, or all this is console releated only? Next, you can power off pc, disconnect/disable your master hdd(new), enable only old and boot from LiveCD(Fedora or any that supports LVM) and rename your old hdd VG vg_alan-fedora to f.e. vg_alan_old, so if there is a problem with naming, you now will have twoo different VG labels. Then connect/enable back your master drive, and boot as now. Then try again to pvscan. In any case be careful, do not damage your data!!!
