As of the LVM in Debian stretch (9.0), namely 2.02.168-2, it's possible to do a copy of a logical volume across volume groups using a combination of vgmerge, lvconvert, and vgsplit. Since a move is a combination of a copy and a delete, this will also work for a move.
You can copy an LVM volume to another the way you'd copy any volume to another: create a target lv of the appropriate size, then copy the contents with dd .
What you can do is transfer one or more PVs from the source VG to the target VG, with the vgsplit command. You can specify which PVs you want to transfer, or which LV (but only one at a . In this article I will show you two methods to migrate a logical volume /dev/rhel/lv1 from one disk to another without reboot assuming you have the extra disk already available on .

Moving LVM volume group from one physical disk onto another

The target disk already contains .Here we will try to do this using LVM2 commands. First let's create a test LV: # lvcreate -n test -L1g /dev/rootvg. .. # mkfs.ext3 -j -m0 /dev/rootvg/test. .. # mount /dev/rootvg/test /mnt/s.

You can copy an LVM volume to another the way you'd copy any volume to another: create a target lv of the appropriate size, then copy the contents with dd if=/dev/sourcevg/sourcelv of=/dev/targetvg/targetlv bs=4M.What you can do is transfer one or more PVs from the source VG to the target VG, with the vgsplit command. You can specify which PVs you want to transfer, or which LV (but only one at a time). If you specify an LV, it and the other LVs in the source VG must be on separate PVs. In this article I will show you two methods to migrate a logical volume /dev/rhel/lv1 from one disk to another without reboot assuming you have the extra disk already available on your system. Below steps are validated on Red Hat Enterprise Linux 7.

First let's create a test LV: # lvcreate -n test -L1g /dev/rootvg. .. # mkfs.ext3 -j -m0 /dev/rootvg/test. .. # mount /dev/rootvg/test /mnt/s. Copy some files on it to verify the integrity of the content later. Now let's make it a mirror.
