Re: [linux-lvm] How to "clone" a logical volume

Hi,

Here's what I'm trying to do:

I have an LV that is being used as a physical disk for a XEN virtual machine.
I want to "clone" the VM.
lvcreate -L 75G -n virtualmachine_clone_lv VG00
dd if=/path/to/virtualmachine_lv of=/path/to/virtualmachine_clone_lvT

This method would be perfect if it wasn't for the fact that now I have
2 LV's with the same uuid....not good...

What UUID are you talking about here? Filesystem UUID, or LVM UUID?

If about LVM UUID, it will not be the same if you dd a LV - UUID is stored somewhere else.

Filesystem UUID (if any) will remain the same, of course, as it's the exact copy.
