Input/output error - disk død?

[Kaplan]

Har en filserver som kjører Ubuntu, har en del disker som er montert i forskjellige mapper. Nå får jeg en feilmelding, betyr dette at disken er død? Finnes det noen stunt man kan gjøre for å berge data? Nyeste backup er nemlig litt eldre enn jeg setter pris på....

 

Har ikke fysisk tilgang på boksen akkurat nå.

 

Her er feilmeldingen:

orjan@boks:/home/orjan$ ls data
ls: reading directory data: Input/output error

 

Etter å ha avmontert:

 

orjan@boks:/home/orjan$ sudo mount -a
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
      missing codepage or other error
      In some cases useful info is found in syslog - try
      dmesg | tail  or so

Stunt finnes det alltids, men det krever i de fleste tilfeller at du har fysisk tilgang til maskinen og / eller disken.

Først ville jeg ha sjekket at kontaktene til disken står ordetlig i, og tatt dem ut og satt dem inn igjen. Hvis det ikke hjelper, se om du får disken til å virke etter at den er blitt kald. Hvis det funker, så kan du kanskje redde data ut "stykkevis og delt" ved å kopiere til disken blir varm, la den kjøle seg ned osv.

 

Til slutt (nest siste løsning) dersom kontrollerkortet på disken er defekt så kan det byttes.

Siste (og dyreste) løsning: IBAS.

Jeg ville vært forsiktig med å berge data "stykkvis og delt" når disken er kald osv. Dette er fordi det er fort gjort å gjøre mer, og i verste fall uopprettelig, skade på disken.
