Comment lancer "fsck" au démarrage?

xico

Hello,
Durant le démarrage d'Ubuntu mon disque dérape sur une trentaine de blocs défectueux:

I/O error, dev sda, sector xxxxxxx
Buffer I/O error on device sda
SCSIO: Error on channel0, id 6

Voici mon /etc/fstab:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/sda2 / ext3 defaults,errors=remount-ro 0 1
/dev/sda3 none swap sw 0 0
/dev/hda /media/cdrom0 udf,iso9660 ro,user,noauto 0 0

Comment faire un fsck?
Pas sur une partition montée!
On ne démonte pas une partition en marche!
Alors comment? Y-a-t-il un argument à entrer dans BootX?

Francois

Salut François,

Est-ce que tu démarres quand même ?as-tu une console ? le net ?
tu peux envoyer la commande de dmesg ?
c'est sur quelle partition ?

xico

Merci de répondre peyo
Oui je fini par démarrer quand même, j'ai une console et le net.

La partition d'Ubuntu doit être sda4:

Partition map (with 512 byte blocks) on '/dev/sda'
#: type name length base ( size )
1: Apple_partition_map Apple 63 @ 1
2: Apple_Bootstrap*untitled 2683594 @ 64 ( 1.3G)
3: Apple_UNIX_SVR2 swap 367188 @ 2683658 (179.3M)
4: Apple_UNIX_SVR2 untitled 5848891 @ 3050846 ( 2.8G)

et voici le dmesg:

EHLO, apparament tu as une partition pour un Mac Os quel version ?
A+

xico

Mac OS 9.2.2

Merci pour tes réponses

Manu_Ubu

EHLO, j'esperais que tu ais Mac Os X car on aurait pu te trouver des outils utilisable dans un shell. Quel BootLoader peux tu utiliser ? seulement bootX ou Yaboot ? . Si tu as beaucoup de mémoire sur ton Mac tu peux essayer d'utiliser un liveCD PPC et lancer une analyse.

Je suis en BootX.
J'ai effectivement beaucoup de mémoire (640M) et j'ai essayé de booter sur le live cd Gentoo. J'arrive dans un prompt me demandant de désigner sur quoi booter ou de choisir le shell où aucune commande fsck ou e2fsck ne fonctionne. Je n'ai pas trouvé les instructions à rentrer à ce moment là.

Merci

Francois

EHLO, perso j'ai utilisé Yaboot mais en lisant une vieille doc (http://www.linux-france.org/macintosh/bootx.html) tu peux avec BootX passer un argument au kernel :"single" pour avoir la console single-user et là peut être tu pourras lancer un fsck . Peut être as tu déjà tester cette commande ?
Sinon pour le liveCD tu peux essayer la Knoppix-MIB-PPC (ftp://ftp.free.fr/mirrors/knoppix-mib.org) elle date un peu mais tu devrais peut être optenir plus de possibilité. Perso je ne l'ai testé qu'une fois car je n'avais pas de Mac dispos avec beaucoup de memoire donc cela était tréééééssssss llllleeeeennnnnnnttttttt 😉

Pour pouvoir faire un 'fsck' sur un Mac : "Pomme"+"S" pendant le boot jusqu'à apparition d'une sorte de console ; là 'fsck' est accessible.
J'ai juste ? :p

Yes 😉

Démarrer en mode "Single User" et taper comme indiqué à l'écran /sbin/fsck -y -f sauf que ça ne fonctionne que lorsque OS X est installé et ce n'est pas son cas.
