377 σε binary = 101111001<br>
337 = 101010001, κάποιοι άσοι γίνανε μηδενικά. Αυτό φωνάζει για disk

<pre wrap="">Τι μας λέει αυτό;
Το filesystem είναι ext3 πάνω σε software RAID-1, με τη σειρά του πάνω
σε δύο πανομοιότυπους δίσκους Serial ATA. Έχω κάνει fsck.ext3 -f -V το
filesystem και δεν ανέφερε κάποιο πρόβλημα. Εκτός αυτού, έχω κοιτάξει
τους δίσκους με smartctl -t long και ενώ αναφέρουν κάποια (όχι
critical) errors, το overalll health αναφέρεται ως ΟΚ. Κάνω attach το
output του smartctl -a /dev/hd[e|g] σε περίπτωση που ξέρει κανείς κατά
πόσο εξηγούνται αυτά που βλέπω από τα λάθη που αναφέρονται σε επίπεδο
hardware.

Πρόσεξε τα error outputs: Ο /dev/hde δίνει ένα write error, ο /dev/hdg
εννιά read errors. Κατά πάσα πιθανότητα το πρώτο submirror (υποθέτω οτι
είναι το /dev/hde) έχει γράψει κάτι στραβά. Σπάσε το mirror και διάβασε
τα αρχεία από τον /dev/hdg να δεις αν από εκεί τα διαβάζει σωστά. <br>
<br>
Αν όντως είναι έτσι, δοκίμασε να κατεβάσεις UltraDMA mode σε udma5
(hdparm -X udma5 /dev/hdg) και παρακολούθα τον πρώτο δίσκο. Τι SATA
chipset έχεις;<br>
