Cloning LVM paritions

[core8583]

Hello,

I'm attempting to clone a LVM partition that contains a copy of my centos OS to another LVM parition, in using the below commands I can get the data over to the other parition but it doesn't boot. I'm guessing that it's something to do with hard links but the error is

Creating root device.
Mounting root filesystem.
mount: could not find filesystem 'dev/root'
Setting up other filesystems.
Setting up new root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.
umounting old /dev

If i use DD i can get this to work but DD copies unused space too which i don't want it to do. Can anyone help?

dd if=/dev/LVM-Storage/OS of=/dev/LVM-Storage/OSNew count=1 bs=512
kpartd -av /dev/LVM-Storage/OS
mkdir /tmp/10
mount /dev/mapper/LVM-Storage-OSp1 /tmp/10
vkpartd -av /dev/LVM-Storage/OSNew
mkdir /tmp/20
mount /dev/mapper/LVM-Storage-OSp1 /tmp/20
cp -p -R /tmp/10 /tmp/20

Thanks in advance.

Just a crazy thought but if dd works for you. Then you could use dd and gzip together. dd would make your bit for bit copy and gzip would eliminate the unused space. Maybe something like

Create image:
dd if=/dev/hdb | gzip -c > /image.img

Restore image:
gunzip -c /image.img.gz | dd of=/dev/hdb
