Доброго дня всем.

Озадачился тут мониторингом  SAS дисков.. и обнаружил что почти на всех
серверах с указанным контроллером (Logic SAS1064ET)

на портах есть ECC ошибки. Причём даже на заведомо новых дисках. В dmesg
ругани на сколько вижу нет,в отличие от smartctl.

Вот например сервер недавно только включил и поставил новый диск.
