It's a bit strange that it outputs nothing at all. I'd expect to see
something like:
$ sudo vgscan -v
Wiping cache of LVM-capable devices
Wiping internal VG cache
Reading all physical volumes. This may take a while...
Finding all volume groups
Finding volume group "scratch0"
Couldn't find device with uuid 'ZpQI30-qpx3-Cm54-YcSR-5Ho4-rlUx-uCxGBi'.
Couldn't find all physical volumes for volume group scratch0.

Volume group "scratch0" not found
If there's a PV missing from the volume group.
You can add move 'v's to increase the verbosity of vgscan to see what
it's scanning - do you have any device filters configured in /etc/lvm.conf?
It'd also be good to see what pvscan shows, for e.g.:
$ sudo pvscan
Couldn't find device with uuid 'ZpQI30-qpx3-Cm54-YcSR-5Ho4-rlUx-uCxGBi'.
PV /dev/hda2 VG d800_vg0 lvm2 [34.18 GB / 760.00 MB free]
PV unknown device VG scratch0 lvm2 [60.00 MB / 0 free]
PV /dev/loop1 VG scratch0 lvm2 [60.00 MB / 52.00 MB free]
Total: 3 [34.30 GB] / in use: 3 [34.30 GB] / in no VG: 0 [0 ]
Once you find the volume group, activate it without the missing PV using
the --patial option, e.g:
vgchange -ay --partial <vgname>
Cheers,
Bryn.
