Titolo: Interpretazione output smartctl

Come interpretereste questo output ?
Notare il Raw_Read_Error_Rate (che tutti dicono di non considerare in quanto non "standard", ogni vendor fa a modo suo) e la totale assenza di settori riallocati di qualsiasi tipo e i long test terminati sempre con successo.
 
Cambio il disco ? Se lo cambio, ne approfitto per migrare a raid sw, questa pseudo-controller hw è molto limitata, ove possibile la declasso a semplice HBA, molti meno problemi e sopratutto posso fare RAID-1 a 3 dischi (come sto facendo ultimamente, visto il costo decisamente inferiore dei dischi rispetto anni fa)

 Preferisci questo con 75000 ore?
 
Bello anche questo. Almeno, sempre stando a SMART.
C'e` da dire che, ad occhio, sono forse pochi
parametri, ma i principali ci sono.
 
Ovviamente, con 75.000 ore e` un candidato migliore...

si ma.... lo cambieresti o no il 40000?
Vedo quei buffi errori di lettura che non saprei come interpretare
 
Il 70000 è su un altro server già con raid se dove l'altro disco in raid1 ha 2500 ore. Posso aspettare che si spacchi il 70000 oppure cambiarlo a prescindere con uno piu capiente almeno faccio spazio
 
Ma non è lui il problema,  ma il 40000

 Ma non è lui il problema,  ma il 40000
 
Se ti riferisci al parametro 1 (raw read error rate),
non credo sia un problema.

piergiorgio

 Non conta niente. E` anche lontano dalla soglia.
 
Si quello. Ho un po di dischi con il raw read error rate alto ma tutto il resto perfettamente sano.


Alcuni disco hanno anche un parametro che
dice quanti errori sono corretti dal sistema
di correzione (credo 195).
Questo numero deve essere uguale al 1.
Detto altrimenti, tanti "raw error" sono
identificate ed altrettanti sono corretti.
 
In questa situazione non ci sono problemi.
 
Questi dischi non sembrano mostrare quante
correzioni sono avvenute.
Non credo, pero`, che sia un problema.
