This may have to do with the fact that kpartx is not integrated into the
rc.sysinit script. Therefore there are no mapped partitions in
the /etc/lvm/.cache.

Make sure your lvm.conf has filters for the disks associated with the dm
device.

Make sure you have run kpartx -a (to map dm partitions)  then restart
the clvm daemon (to populate the cache with the partitions).

This is an issue with RHEL4 U2. I haven't checked FC4.
