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

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.
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;
