Hmm...  Was any of the physical volumes a raid member in a former
life?  vgscan now discards block devices that contain raid superblocks
at the end.  Boot in rescue mode and use mdadm --zero-superblock to
remove the superblock from any former raid devices.

Then, run lvm vgscanto see if it can find the volumes.  If it doesn't,
keep adding `-v's until it tells you why :-)
