It is quite easy to move a whole volume group to another system if, for example, a user department acquires a new server. To do this we use the vgexport and vgimport commands.
First, make sure that no users are accessing files on the active volume, then unmount it
# unmount /mnt/design/users
Marking the volume group inactive removes it from the kernel and prevents any further activity on it.
# vgchange -an design vgchange -- volume group "design" successfully deactivated
It is now necessary to export the volume group. This prevents it from being accessed on the ``old'' host system and prepares it to be removed.
# vgexport design vgexport -- volume group "design" sucessfully exported
When plugged into the new system it becomes /dev/sdb so an initial pvscan shows:
# pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/sdb1" is in EXPORTED VG "design" [996 MB / 996 MB free] pvscan -- inactive PV "/dev/sdb2" is in EXPORTED VG "design" [996 MB / 244 MB free] pvscan -- total: 2 [1.95 GB] / in use: 2 [1.95 GB] / in no VG: 0 
# vgimport design /dev/sdb1 /dev/sdb2 vgimport -- doing automatic backup of volume group "design" vgimport -- volume group "design" successfully imported and activated
