Я купил Centurion Nano у ныне несуществующей Alpha Computers, она поставляется с Alpha OS (то есть, по сути, с подделкой Ubuntu):

Сегодня, после загрузки, я заметил, что мой / mount только для чтения, я перезагрузился и получил это сообщение:

Inodes that were part of a corrupted orphan linked list found.
UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

на /dev/sdb2 . Так как это происходит во второй раз за 1 месяц, я хотел бы понять, что может быть причиной, и как я могу убедиться, что это больше не повторится? В первый раз я думаю, что система зависла при выключении, и я выключил ее. На этот раз завершение было успешно завершено (или я так думал).

Вот более подробная информация о диске:

ОБНОВИТЬ

Это все еще происходит, я предпринял следующие случайные меры в надежде исправить ситуацию, но безрезультатно:

  • удалил зашифрованный пользовательский дом (теперь весь диск представляет собой обычный ext4 без ecryptfs)
  • удалил шифрование из свопа и перенёс в файл свопинга на другой диск
  • обновил ядро до 4.15.0.42.63 amd64 [от: 4.15.0.29.51]

Я чувствую, что проблема возникает, когда система перегружена, но это может быть легко наоборот (ошибки -> только для чтения fs -> chrome и другие приложения чувствуют себя медленно).
