Re: [linux-lvm] Error after moving volume group to another machi

["Heinz J . Mauelshagen" <mauelshagen@sistina.com>]

Florian,

is it really 3 HDDs you want to move, not 4?
It says "Cur PV		4" in the pvdata output below.
Maybe that still makes sense, because you have 2 PVs in 2 partitions on
the very same physical disk.

That pvdata reports an empty VG name is just a minor flaw but doesn't show
an error.
