Unfortuately this project is mostly RHEL4 boxes (its an old SAN, nothing new has been added to it in a couple of years) and so thats what I've been testing with (RHEL4.5 to be precise) so if you really want me too I'll file a bug but I'm pretty sure it will just get closed with "upgrade to a modern version of lvm" :)
