That line makes volume group active. 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!!!

how to rename>>>
livecd# pvs
livecd# vgscan
livecd# vgchange -a n
livecd# vgrename vg_alan-fedora vg_alan-old
