Salutare!
A mai intalnit cineva urmatoarele erori?
(configuratia:
Debian Lenny x64 + Xen + mdadm raid1 sda + sdb - Seagate
ST31500341AS)
Dupa ce mi-au aparut ieri urmatoarele mesaje in dom0:

Acum imi apar odata la
cateva ore urmatoarele notificari:
Oct 15 06:30:40 smartd[3663]: Device:
/dev/sda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from
105 to 113
Oct 15 06:30:41 smartd[3663]: Device: /dev/sdb, SMART
Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 116 to
117
Raw_Read_Error_Rate-ul a fluctuat toata ziua intre 100 si 120. Vreo
idee?
Eu din cate am citit pe forumuri, pare a fi o problema de
incompatibilitate intre chipsetul placii de baza si harddisk-uri (dar ar
fi trebuit sa mai am erorile astea pana cum prin loguri... ceea ce nu
s-a intamplat). Se recomanda schimbarea firmware-ului la disk sau a
placii de baza ceea ce e foarte complicat. Sistemul are un uptime de
+300 de zile, iar mesajele de mai sus au inceput de ieri. Sistemul este
destul de solicitat in general. (VPS-urile uneori ating load average-uri
de 10-15 sau chiar mai mari)
PS: dezactivarea NCQ-ului ese exclusa...
