[linux-lvm] How to activate a vg or lv with same name as active one

[Heinz J . Mauelshagen]

Frank,

you needed to export the volume group *before* you moved the physical devices
over to the other system :(
After the move you needed to import the volume group giving it a new name.
See vgexport(8) and vgimport(8) for this.

In case you can't move the disks back to achieve this, the only option is
to patch your metadata at the beginning of each of the physical volumes
and change all occurences of vg_sys to vg_WhatEver (hacky!).
