Недавно я установил LVM на Ubuntu 18.04, запущенную на физической рабочей станции, а затем создал свой первый LV. После первой перезагрузки я обнаружил проблему, так как я больше не могу его активировать.
Я заметил эту ошибку:
root@lvrome:/var/log# pvdisplay -v

Я попытался принудительно активировать VG, а затем LV, но не могу продолжить:

Я уверен, что не изменил размеры PV после установки. Кстати, я создал их через pvcreate /dev/sdb /dev/sdd, vgcreate backup_vg /dev/sdb /dev/sdd, lvcreate --type striped -i 2 -l 100%FREE -n backup backup_vg.

Можете ли вы помочь мне найти решение?

Порядок перечисления дисков не сохраняется между перезагрузками. Поэтому /dev/sdbи /dev/sddмогут быть изменены на противоположные при каждой перезагрузке системы. Или переключены с помощью /dev/sdaили /dev/sdc. Или что-то еще.
Если вы делаете что-то, что зависит от обращения к одному и тому же физическому диску при каждой загрузке системы, лучше всего использовать символические ссылки, /dev/disk/by-idпоскольку Linux гарантирует, что они всегда указывают на одни и те же физические диски, даже если их /dev/sd*особенности меняются.
Например:
pvcreate /dev/disk/by-id/ata-SEAGATE-ST3160813AS_*whatever # you hid the serial number
Технически этоне следуетможет быть необходимо с LVM, поскольку он использует собственные UUID для всего, по крайней мере после создания физических томов, но это хорошая привычка.
