[Résolu] Problème au démarrage : erreur sur une partition
Bonjour à tous !
Suite à une mise à jour de php, mon système a refusé de redémarrer, j'ai dû éteindre sauvagement car la demande de reboot me ramenait systématiquement sur l'écran de login.
Je suis sous Xubuntu 16.04 LTS.
Au démarrage maintenant j'ai cette erreur :
Kernel panic - not syncing : Attempted to kill init! exitcode=0x00007f00puis quelques lignes plus bas :
drm_kms_helper: panic occured, switching back to text consoleJ'ai donc booté sur une distrib live USB et effectué les commandes suivantes avec leurs résultats comme conseillé dans le post [Récupération de données] Aide et centralisation des cas :
root@kali:~# sudo sfdisk -luS
Disk /dev/sda: 121601 cylinders, 255 heads, 63 sectors/track
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.

root@kali:~# mke2fs -n /dev/sda1
mke2fs 1.42.5 (29-Jul-2012)
/dev/sda1 alignment is offset by 1024 bytes.
This may result in very poor performance, (re)-partitioning suggested.
mke2fs: inode_size (128) * inodes_count (0) too big for a
filesystem with 0 blocks, specify higher inode_ratio (-i)
or lower inode count (-N).Il semblerai suivant le résultat de cette commande que ce soit un problème de "magic number in superblock" :
root@kali:~# fsck /dev/sda
fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>j'ai essayé la commande suggéré mais sans succès...

Je n'arrive pas à avoir une liste de superblock.
Si quelqu'un pourrait m'éclairer ce serait au top 
Merci d'avance !

Mais sda1 n'est pas une partition réelle il faut remplacer 1 par 6 puis faire la même chose avec la valeur 7
tu feras aussi cette commande avec un petit a elle donne plus de chose car l'état du disque n'est pas excellant

Re : [Résolu] Problème au démarrage : erreur sur une partition
Bonjour
Non les pre-fail ne veulent pas dire que le disque va lâcher
Elles veulent simplement dire que le smartcctl stocke dedans des chiffres qui peuvent signifier que le disque va lâcher
Dans ton contexte tu as
1 Raw_Read_Error_Rate 0x000f 108 099 006 Pre-fail Always - 17519704
3 Spin_Up_Time 0x0003 098 098 000 Pre-fail Always - 0
5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
7 Seek_Error_Rate 0x000f 069 060 030 Pre-fail Always - 4304794133
10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0Tu devines qu'une valeur 0 ne signifie pas que le disque lâche mais qu'une valeur de 12 chiffres est très inquiétante.
Or tu as deux compteurs qui sont assez important. J'ai donc voulu en voir un peu plus
