Eu tenho uma VM com 2 discos e 2 VG, um dos discos é um PV (sem partição). O sistema operacional é CentOS 7. Agora o disco está indisponível. O PVS exibe:
# pvs

Aborting vg_write: No metadata areas to write to!
Tentei adicionar um dispositivo de loop para gravar metadados:

# vgextend vgbackup /dev/loop0

O PV /dev/loop0 foi criado, mas não anexado ao vgbackup:

O que fazer agora? Como posso remover o vgbackup da configuração do lvm? Reiniciar não é uma opção agora.
Obrigado pela ajuda!
