Bon, bah, c'est fini. Pas eu de coupure EDF, mais visiblement, y'a un truc qui a foiré :o(
J'ai attaché les logs... D'après ce que je comprend, il a bien déplacé le système de fichiers,
puis la partition elle-même, mais le checkdisk final n'est pas content : il voit une
discordance entre la taille de la partition et du système de fichiers...
Une idée pour rattraper ça ? Je reboote, tout simplement, où faut-il intervenir avant ?
Merci d'avance.
UPDATE :
Entre-temps, j'ai contacté Edgar en privé, qui m'a donné le conseil suivant :
"Personnellement je serais tenté d'y aller à la
tronçonneuse : éditer le superbloc à la main avec dd et hexedit (pas vim
pour une fois...). Tu dois mettre à jour au moins s_inodes_count,
s_blocks_count, s_free_blocks_count et s_free_inodes_count [1]. Ensuite
recopier ça dans les backup superblocs, sauf s_block_group_nr qu'il faut
pas changer. Éventuellement corriger aussi bg_free_blocks_count et
bg_free_inodes_count du dernier group descriptor. Et passer e2fsck
derrière pour t'assurer que tout est bon. Mais pour ça il faut commencer
par faire un dumpe2fs, établir une carte détaillée de ce que tu dois
modifier à quel endroit, et s'armer de beaucoup de patiente..."
J'ai commencé à regarder les outils bas niveau, et ça va être marrant ;o)
Si quelqu'un a d'autres pistes, avant que je casse tout, je suis preneur.
Je me demandais par exemple comment forcer resize2fs a remettre la bonne taille. Là, il râle,
et veut à tout prix que e2fsck remettre le file systèm en ordre. Mais e2fsck n'y arrive pas
(j'ai tout essayé plein de trucs, comme lui donner un backup du superblock, mais il me demande
de corriger des milliards d'i-node, et répondre y à chacun, c'est pas de la tarte. Et
l'option -y n'aide pas, car la première réponse, c'est 'do you want to abort?' !!! Donc -y fait
sorti tout de suite...)
