Question

LVM «не запускается» после обновления физических дисков в базовом массиве RAID6 mdadm

До:

отдельный загрузочный диск SSD
RAID6 4 x 2 ТБ ->
ЛВМ PV
LVM VG построен на фотомодуле, указанном выше.
Разделы данных LVM 2, сформированные в VG
- установлен на/homeи/mnt/data
Я обновился с Ubuntu 20.04 до 22.04 (после перезагрузки все работало)

Вышеописанное работало хорошо, но я обновил диски емкостью 2 ТБ до 3 ТБ и добавил пятый диск, в результате чего получился RAID6 5 x 3 ТБ.

Я не разбивал новые диски, я просто сделалmdadm --fail/mdadm --removeна каждом старом диске емкостью 2 ТБ, а затемmdadm --addдля нового диска емкостью 3 ТБ, позволяя каждому синхронизироваться перед переходом к следующему (следя заcat /proc/mdstatпрогресс).

The mdadm --detail /dev/md0показывает все активно, все 5 дисков в хорошем состоянии. Суммируя,/dev/md0выглядит отлично. Он прекрасно переносит перезагрузки.

Однако при загрузке у меня возникают проблемы с настройкой LVM. Если я запускаю команды LVM с помощью-vvмногословие, они показывают, что группа томов LVM «видна», но по какой-то причине это не происходит из-заWARNING: device /dev/md0 is an md component, not setting device for PV.
