Couldn’t find PV pv1. Check your device.map

Виртуалка на базе KVM с lvm2 внутри.
В свое время для увеличения дискового пространства был добавлен второй диск.

И вот при очередном обновлении ядра вылезла ошибка:

Running update-initramfs.

При просмотре файла /boot/grub/device.map увидел, что там указан только один диск:

# cat /boot/grub/device.map 
(hd0)   /dev/vda
#

После добавления второго диска в /boot/grub/device.map:

# cat /boot/grub/device.map 
(hd0)   /dev/vda
(hd1)   /dev/vdb

обновление завершилось без ошибок:

Что и требовалось.
