Я запустил badblocks -v /dev/sda, который не вернул ошибок.

I тогдаrun smartctl --all /dev/sda, который также не вернул ошибокСмотрите вывод ниже.Этот включает в себя короткий самопроверка

Мой вопрос прост: что, по вашему мнению, может быть не так?SSD должен быть совершенно новым.Мне с чистой совестью сложно запустить этот сервер с такими ошибками в логах.И в остальном коробка работает нормально.

Answer 1

Ошибки, которые вы видите, являются ошибками интерфейса, они происходят не от самого диска, а от соединения с ним. Это может быть кабель или любой из портов в соединении.

Поскольку ошибки CRC на накопителе не увеличиваются, я могу только предположить, что проблема связана с приемной стороной используемой вами машины. Вы должны проверить кабель и попробовать другой порт SATA на сервере.
