It should be one of the news in rh el 5.3.
See at http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Release_Notes/index.html
LVM-based Cluster mirroring
    With this update, the ability to create LVM mirrors in a cluster
environment (i.e. while using CLVM) is now available in Red Hat
Enterprise Linux It provides for simultaneous access from multiple
cluster machines, like when using a cluster-aware file system. This
solution is compatible with existing single-machine mirrors. When
switching a mirrored logical volume between single-machine and
cluster-aware, no resynchronization is necessary.

Not tried yet though.
