Эта система имеет загрузочный раздел на устройстве dm-raid.
Я обновил систему стандартными методами со старой Ubuntu до последней LTS. Теперь, если ядро обновляется с помощью «apt-get upgrade», новое ядро не загружается. На загрузочном экране GRUB также отсутствуют записи.
Я определил, что update-grub работает так, как я ожидал, обновляя раздел, смонтированный в / boot. Однако, когда я загружаю его, GRUB читает корневой диск / загрузочную папку. Он не монтирует рейд isw_dbbbejgeca_Volume0p1 в / boot перед запуском.
Если я скопирую содержимое смонтированного / загрузочного диска в папку, а затем отключу его и скопирую все содержимое в корневой диск / загрузочную папку, система загрузит новые ядра и покажет все обновления в меню GRUB.
Мне нужна помощь, чтобы убедиться, что GRUB смонтирует загрузочный раздел на основе рейда.
Далее приведены некоторые результаты работы средства восстановления загрузки.

Я не уверен в предложениях.
The boot flag would be placed on sdc1.
sdc1 - это резервный диск, он не всегда будет там. Думаю, мне не нужна загрузка с этого диска.
Я беспокоюсь, что это может перестать загружаться. Для восстановления загрузки требуется Интернет, но этот сервер не будет иметь доступа к Интернету.
Итак, я прошу вас поделиться некоторыми командами grub для выполнения других шагов:
purge and reinstall the grub2 of mapper/server01-root into the MBR of sdb, using the following options:
mapper/isw_dbbbejgeca_Volume0p1/boot,
Additional repair would be performed:
unhide-bootmenu-10s
Это описано в вики Ubuntu. Может быть, в первую очередь следовало спросить там. Сожалею. Но на случай будущих посетителей. Вот это ссылка. Однако конфигурация рейда не допускала установку на / dev / sdb, как указано в boot-repair. Установка должна идти на основной том рейда. Вот это другая ссылка об этом.
