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) to check if
this is the issue you have.

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