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).
