I think your understanding of CLVM may be wrong. CLVM will not make 
volume groups etc on local storage available to both nodes - its used to 
manage shared storage. Storage is presented to both nodes (ie, a SAN or 
iSCSI) and CLVM is used to manage the storage (ie, prevent metadata 
corruption by using locking, and making sure that both nodes have a 
consistent view of each VG etc).
