rhn rpm database sync?

Folks,

I had to partition off space for /var a couple days ago (was just one 
big chunk of memory before). I copied all the files over from the old 
/var space to the new partition and everything seemed fine.

However, redhat has now forgotten what packages I have. I've tried rpm 
--rebuilddb . It exits immediately with no errors. rpm -qa shows no 
packages (but i have a bunch of them obviously).

Is there a way that rhn can tell my system what packages it has? 
rhn-profile-sync does something similar, but the opposite direction.

Thanks!

Mike
