I would try this myself to rename the lvm. I believe there are also 
volume labels for / and swap on your lvm. Since I am by no means an 
expert on lvm usage, I checked to see if by chance there was a list 
dedicated to lvm usage on Linux. There is a list.

Renaming the lvm to not confict with existing volumes. Relabeling the 
volumes to /oldroot or something similar is what seems needed.
It is great that my advise did not end up in dataloss for you yet. See 
if the list is of any help first.
It sounds like you are making some progress on finding utilities in lvm 
to get at the data.
