Partimage can't use LVM

[Simba]

I want to backup my LVM partition with knoppix cd , so after I boot the knoppix cd, I run vgscan and vgchange -ay to make my lvm partition
available., and yes I can mount my lvm partition and see the content. But
if I use partimage, I can't see my lvm partition at all, I can see only the normal partition. during startup of partimage I get several warnings tell me
that /dev/lvma /dev/lvmb ... is not exists and will be created, and I confirmed that partimage should created it, but when I try to find /dev/lvma /dev/lvmb .. , they are not created, I have only /dev/lvm created by vgscan/vgchange. should I create /dev/lvm[abc..] manualy with mknod?
and how?
or someone know how to make lvm partition available to partimage?
thanks,
Simba

--I don't think partimage is designed to work with LVM. Usually partitions are 1 unit, not several units logically bonded into 1. But did you check the man page?

--If partimage isn't going to do the job, I suggest you try tar.

yes, partimage can work with LVM, I did use it with gentoo installer cd.
It would be nice if knoppix can do also the same job (both partimage in knoppix and gentoo cd has the same version).
