MessaggioOggetto: Problema di RAID 0   Mer Dic 12 2012, 14:37

Per avere la directory /home più veloce la avevo montata su un raid (meglio fakeraid) 0.
Dopo un po' di tempo, circa un anno ho cominciato ad avere problemi di file system danneggiato, che fsck riusciva a riparare, ogni volta che accendevo il pc dovevo fare fsck.
Ho pensato che un disco avesse dei settori danneggiati.
Ora ho spostato la home un un altra partizione, ho formattato i dischi e badblocks con l'opzione -w non rileva errori su nessuno dei 2 dischi.

Gestione dischi mi dice che i dischi sono ok, ma vedo dei valori strani, più precisamente:


sdb
1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0

sdc
1 Raw_Read_Error_Rate 0x002f 199 199 051 Pre-fail Always - 351


Così non so se ho un disco che sta andando oppure no.

muro


Qui l'output dei comandi
