Bonsoir,
      
lu
Sur mon serveur, à part ma partition de boot, tout le reste est en
LVM. Là, je viens d'avoir une micro-coupure EDF et, au retour du
courant, Debian ne retrouve pas ces petits : du genre la partition
de tel UID n'est plus accessible...
      
Les messages "Du genre" ne sont jamais vraiment utiles. Par contre, le
vrai message d'erreur peut servir, des fois ;)
    

Oui, mais là, y'en a plein ;-)
Alors, après analyse rapide, il semblerait que les 3 premiers disques
aillent bien, mais pas le 4ème.
J'ai donc : /dev/sdd ne contient pas une table de partition valide...

Donc, je ne peux pas faire de fsck.ext3 car les partitions ne sont
mêmes pas vues... Et en plus, sur du LVM, je ne sais même pas ce que ça
donnerait...

  
Un fdisk -l me montre bien les volumes, mais j'imagine
qu'il doit y avoir des manipulations spécifiques à faire...
      
Essaye déjà de les monter, en ro éventuellement. Et dis-nous ce que ça
dit.
    

Ben là, je n'y ai même pas accès...

  
Avant de faire des bêtises (ce serait bête : j'ai tout dessus !),
      
Et bien sûr, pas de sauvegardes, hein? :)
    

Si, quand même... Mais bon, pas sur les 15 derniers jours...

  
j'aurais voulu savoir comment agir dans ce genre de cas...
      
Appeler Mme ALBANEL: Ils ont les backups de tous les utilisateurs de
GNU/Linux, au cas où :p
    

Je vais d'abord tenter le reste ;-)

Merci.

David.

  
lvscan te donne quoi?

tu peux aussi avoir des info en faisant un lvdisplay

cela devrait te donner une idee de l etat de tes hd / partitions
