Tengo una máquina virtual con 2 discos y 2 VG, uno del disco es un PV (sin partición). El sistema operativo es CentOS 7. Ahora el disco no está disponible. El PVS muestra:

Intenté agregar un dispositivo de bucle para escribir metadatos:

¿Qué hacer ahora? ¿Cómo puedo eliminar vgbackup de la configuración de lvm? Reiniciar no es una opción ahora.
¡Gracias por su ayuda!
