Сервер с 3 SSD дисками (рейд софт). CentOS 6, ядро 2.6.32 ovz (последний стабл).
Разделы сделаны так
/ => raid1
/boot => raid1
/vz => raid5
Сервер пустой. Несколько раз в день в логах появляются ошибки на дисках sdb и sdc
Воспроизвести под нагрузкой не получается, происходит периодически.

По смарту с жесткими дисками - все окей.

На данный момент, сделал без рейда, разбил на /sda, /sdb, /sdc -> нагружаю диски, пытаюсь воспроизвести.
Может быть кто-нибудь сталкивался с подобной проблемой?
Думаю что проблема в шлейфах или с жесткими дисками. Заменить их сам не могу - веду переписку с ДЦ.
