DESCRIPTION
vgimport allows you to make a Volume Group that was
previously exported using vgexport(8) known to the system again,
perhaps after moving its Physical Volumes from a different
machine.
Essentially, IIUC, vgexport updates the LVM configuration to remove the
group from the system. I *guess* it might also put some status
information into the descriptors on the volume being removed so that
critical information is available when a vgimport is done.
I can tell you from first-hand experience that moving the volume without
doing this makes for extra work when re-installing, though I can say
that it can be done. Again, from first-hand experience.

One of the *few* advantages to not using LVM. Overall, I'd rather use it
in most cases.
