Jared is assuming here that you have identically named VGs and LVs. If that
is not the case, only his step 5 applies.  This is a logical leap, because
you are mostly communicating frustration and simply mounting a filesystem
on an LV isn't difficult or fundamentally different from mounting a
filesystem on a normal partition - blkid to list filesystems and their
device nodes, then fstab or mount manually.

If you do have identically named VGs and LVs, did you create them during
installation? Was the older installation visible during the process?
