Hi,

You will need to manually create the new lvm on the other server, it should be exactly the same size as on the source server then use dd to clone the partition. Run this on the source server:

Code:

dd if=/path/to/volume of=/path/to/some/external/drive/with/lots/of/space/dd.image

and to restore the partition on the destination server you need to boot from live cd:

Code:

dd if=/path/to/some/external/drive/with/lots/of/space/dd.image of=/path/to/volume

java socket

depending on how your boot loader is setup you will need to copy that as well.

Either way you can use LVM's export and import commands to achieve the same.

Try GOOGLE..you'll find lots of stuff related to this...
