I have cloned one RedHat disk to another using "dd" but now cannot boot unless one disk or the other is physically removed. The disk uses LVM with the /boot using lvm2 format. I think the problem is that GRUB sees identical boot blocks. Is it possible to change an lvm2 format boot LABEL so that GRUB sees 2 different labels? This is easy for ext2 or ext3 using e2label but I have found no way to change an LVM, lvm2 format, label for /boot.
Thanks in advance,
