LVM2-2.02.64 patch: http://people.redhat.com/msnitzer/patches/multisnap/lvm2/LVM2-2.02.64/
but when I used it, the segment type can not find, can anyone help me?
[root@new-host-34 ~]# pvcreate /dev/sd[bcdef]

I just want to use the multisnap by LVM2 command. But I don't know is there any document about HOW-TO?
Thank you very much.
