Alguma ideia para remover vg?

    

Answer 1

Você não pode usar --removemissing ou force delete VG se a área de metadados for igual a zero como no meu caso.

Crie o dispositivo de bloco a partir do arquivo e inclua no VG:

dd if=/dev/zero of=/tmp/tmp.raw bs=1M count=100 losetup -f losetup /dev/loop0 /tmp/tmp.raw vgextend $VG /dev/loop0

Depois disso, tenho Metadata Areas 1

vgremove $VG -force

e remova pvdevice pvremove /dev/loop0

    

Answer 2

Execute vgreduce --removemissing $VG primeiro. Isso removerá todos os LVs "parciais" - ou seja, todos os LVs que usam o disco ausente. Homem: vgreduce (8) .
