Re: raid error debian

["Alessandro A." <atax@email.it>]

allora,

ho analizzato il disco con smartmontools , tutto ok
allora ho provato a reinserire il disco in raid con la procedura 
mdadm --add /dev/md0 /dev/sdc1

e ha reiniziato il sync

ha finito, ho rigenerato init e ho riavviato

ora ho una situazione del genere:

 mdadm --detail /dev/md0

ma cosa può essere stato??? calo di tensione?

mentre riparavo tutto tenevo il case aperto mi è capitato per sbaglio di sfiorare i cavi di alimentazione 
di un harddisk serial ata 
appena l'ho toccato si è sentito un rumore strano provenire dall'hd

siccome avevo aperto tail -f /var/log/messages mi è comparso questa lista di errori:

ora il raid funziona e faccio qualche altra prova con smartmontools e poi si vedrà

praticamente certo un problema hardware. Che sia disco, cavi, controller
(scheda madre) o alimentatore (o meno probabilmente, ram o cpu), non so
dire.
