grob probleme pour reinstaller un kernel-image sur un debian chrooté



Bonjour,

Je voudrais me remettre un kernel-image sur ma debian sarge qui ne boote plus (à
cause d'un kernel 2.6.16 de backports et en voulant mettre le udev de backports
il m'a viré hotplug + kernel-image-2.6.8 de debian sarge donc plus moyen de
booter sur le bon noyau)

Le soucis, c'est que j'utilise du raid + lvm2...

J'ai reussi avec mdadm à trouver toutes mes partoches raid, et ensuite avec
vgchanges, à faire reconnaitre mon Vg, et mes LVS.

J'ai monté mon LV qui contient la partition /:

mount -t ext3 -rw /dev/VG0-SLASH /mnt/debian

je chroote:

chroot /mnt/debian

Et de là, quand je veux installer le kernel-image avec aptitude, il me dit:

/usr/bin/mkinird: /dev/mapper/VG0-SLASH: unknown root device au moment de
l'ecriture de l'initrd

J'ai rechrooté sur ma debian sargedepuis la knoppix et en faisant un vgchange
-ay (euh je crois que c'est ca)

Il a enfin reussi à creer l'initrd, mais mnt j'ai ca au boot:

Uniable to find volume group VG0
pivot_root: no such file or directory
/sbin/init: 432: cannot open /dev/console
kernel panic: attempt to kill init


Pourtant tout est nikel qd je chroote sur ma debian sarge depuis la knoppix, il
reconnait mon VG et mes lVs.....
