SCSI winyo hiba?

Sziasztok,

Adott egy gep, benne ket 36 gigas SCSI vinnyogo, RAID 0-ba szervezve.
A gep kb 200-300 napja folyamatosan be volt kapcsolva, eddig nem volt vele semmi baj. Tortent egy aramszunet a szolgaltatonal, es ujraindulaskor /var/log/messages fileban a kovetkezo csunyasagokat talaltam:

Ugy tunik, hogy ez nem tul jo, Ime meg par parancs kimenete, hatha segit az analizisben:

Aggaszt az sda eseten a "total errors counted" ertek. Mit tanacsoltok? Azonnali backup, es toljunk be uj winyot az sda helyere? Fsck meg nem volt, egyenlore elfele masolok mindent...

Thnx minden segitseget: reluxa
