The following is an example of how to transfer a partition from one server to another.
In the example, I first create a file containing the partition, and then transfer the partition to the other server.
dd if=/dev/xen-1/aktagon.com-disk of=/tmp/file scp /tmp/file [email protected]:/file
I then SSH to the other server and create the partition from the file.
ssh host lvcreate -L 4G /dev/VG00/aktagon.com-disk cat aktagon.com-disk.bz2 > /dev/aktagon-1/aktagon.com-disk
Remember to create a backup before running these commands.
