I have a question about making copy of LVM partition to new disk. I want co copy not to move data.
My operating system is Debian. On LVM partition I have running Xen virtual systems.
Information about my disk with LVM (/dev/sdb):
root@server:/# fdisk -l /dev/sdb
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

At the moment I made copy of all non LVM partitions to new drive (dev/sda):
root@server:/# fdisk -l /dev/sda
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors

Partition 3 does not start on physical sector boundary.

Correct me if I'm wrong but should I follow these steps:
- Change partition type to LVM on /dev/sda8
pvcreate /dev/sda8
vgextend VG /dev/sda8
lvconvert -m 1 --mirrorlog corelog VG/lvol1 /dev/sda8
- for all logical volumes.- To see the progress
lvs -a -o+devices
lvconvert -m 0 VG/lvol1 /dev/sda8
- for all logical volumes.
