Re: [RiminiLUG-General] problema Input/output error su alcuni files

se lancio ls ricorsivamente nella mia home:
gio@debian:~$ ls -lR | grep "Input/output error"
ottengo una lista di una decina di file.
Sembra il filesystem sia corrotto. Prova se con fsck scompaiono i problemi.
Sul perché si sia corrotto non so: controlla se ci sono stati errori nel
disco con sudo smartctl -l error /dev/sd??
In bocca al lupo al tuo hd

Grazie per le indicazioni, riporto alcuni risultati e altri quesiti.

[In fondo riporto i risultati di smartctl -a /dev/hda]
Poi da un rescuecd ho lanciato *fsck* e mi sono comparsi vari messaggi
(me li sono segnati a penna... potrebbero essere leggermente diversi):
66193 is in use but has dtime set Fix<y>?
66193 has imagic flag set Clear<y>?
66193 has a extra size (65276) which is invalid Fix<y>?
[...] lo stesso per gli altri inode
e poi:
66193 has compression flag set on filesystem without compression support
[...] i-blocks is [numero] should be 0 Fix<y>?
Ho risposto y a tutti... alla fine riavviando non ho più l'errore sopra,
e i file sono stati cancellati.
Mi è capitato altre volte di avere problemi all'avvio, con la necessità
di lanciare fsck e fargli riparare tutto in automatico... questo
immagino avvalori l'ipotesi di un disco un pò in bilico...
A proposito di fsck mi sapete indicare un link a materiale che spieghi
in modo semplice il funzionamento e l'uso più comune?
Altra cosa riporto il risultato di fdisk -l /dev/hda:

Come vedete ci sono due avvertimenti relativi alle partizioni windows
(ricordo di avere sempre avuto questi avvertimenti). Possono essere la
causa dei problemi o crearne?. Come faccio a mettere a posto queste
cose? Vi sembra corretto il modo in cui è partizionato il disco?
Grazie per l'aiuto,
giovanni
