My LVM is working great but lvm utilities show - only, when using -o
devices, that I have multiple copies of the same pv, vg and lvs. See
below, the first invocation is what I would expect (one PV 'nvme0n1p2',
one VG 'vg1', four LVs 'home' 'log' 'rootfs' and 'swap') but in each
case the second invocation (i.e. with -o +devices) shows multiple
versions of the same thing.
This may be because I copied my disk to another using clonezilla and
subsequently copied the new disk back to the original using dd. I'm now
only using the original disk. Although I am also seeing (not shown
below) duplicate devices for a 2nd PV and VG and LVs which are on a
second disk on the same machine - and this second disk was unchanged
throughout the process.

As I say, this has not caused a problem so far, but it is certainly ugly
and looks like it might cause problems in the future. Should I ignore it
or any ideas how I can fix it?
