Я просто перепрофилировал 4 диска, которые долгое время не использовались, и установил на них arch linux (сырые диски -> mdadm -> dmcrypt -> LVM -> ext4). При создании LVM у меня были «ошибки чтения ATA» для каждого диска, но в конце было указано «успех». Теперь, когда у меня все работает, я начал настраивать smartmontools и на коротком тесте получил ошибки. Обычно я просто думаю, что они старые и дефектные, но странно то, что все диски получают эту ошибку в одном и том же LBA одновременно.
Это smartctl -a для одного диска, но все они очень похожи с небольшими вариациями в времени работы / времени работы. Ключевым моментом является эта ошибка LBA_of_first_error, которая идентична на всех дисках с номером 24.

У кого-нибудь есть объяснение этому? На мой вкус, совпадений мало или много. Какие-нибудь известные ошибки в Arch или mdadm?
Я собираюсь запустить плохие блоки на этих дисках, потом сообщу.
PS: предупреждение о потере данных можно игнорировать, так как на накопителях установлено необходимое обновление прошивки
