SOS!!! RAID 0 EXT 3 ! Πως επανακτώ τα αρχεία μου;

[StavrosD]

Γεια,

Είχα 2 δίσκους σε εξωτερικό case που έχει linux, και είχα βάλει 2 δίσκους σε raid 0 και για σύστημα αρχείων είχα επιλέξει EXT3.

 

Ο ένας δίσκος μάλλον έχει πρόβλημα και δεν τον βλέπει, αλλά στο PC φαίνεται κανονικά.

 

Ξέρει κάποιος να μου πει κάποια βασικά βήματα ώστε να κατεβάσω μια live διανομή , και να κάνω mount τους δίσκους ως raid 0;

Δοκίμασε να ξεκινήσεις με το minimal installation cd του Gentoo (μπορείς να το κατεβάσεις από εδώ).

 

Δώσε:

># modprobe raid0

Αν δεν έχουν δημιουργηθεί αυτόματα device nodes (/dev/md*), φτιάξε μερικά να υπάρχουν:

 

># mknod /dev/md1 b 9 1
# mknod /dev/md2 b 9 2
# mknod /dev/md3 b 9 3
# mknod /dev/md4 b 9 4

 

και στη συνέχεια δοκίμασε να κάνεις assemble το array με τη mdadm. Π.χ. αν οι δίσκοι από τους οποίους αποτελείται είναι οι /dev/hda και /dev/hdb, δώσε:

 

># mdadm --assemble /dev/md0 /dev/hda /dev/hdb --verbose 

 

Αν όλα πάνε καλά, το ext3 filesystem θα είναι διαθέσιμο στο /dev/md0, και θα μπορείς να το κάνεις mount ή fsck:

 

># mount /dev/md0 /mnt/gentoo
ή
# fsck /dev/md0

 

Ελπίζω να μην ξέχασα κάτι. Αν σε κάποιο σημείο δεν προχωρήσει όπως πρέπει, παράθεσε το μήνυμα λάθους, καθώς και τυχόν σχετικά μηνύματα από το kernel log (που μπορείς να δεις με την dmesg).

Γεια σου master!

[StavrosD]

Πριν το δοκιμάσω, είπα μια τελευταία φορά να δοκιμάσω στο NAS και λειτούργησε.

Στο SMART δεν λέει pass, αλλά NONE (το ξανάτρεξα και διορθώθηκε σε pass).
