grub2-mkconfig -> erreur : unknown LVM metadata header.

llaumgui

Bonjour,

j'ai un problème lors de la génération de mon fichier de conf de GRUB2 :

root@enterprise /home/llaumgui> grub2-mkconfig -o /boot/grub2/grub.cfg
Création de grub.cfg…

Je ne comprend pas mon LVM est bon :

root@enterprise /home/llaumgui> pvscan                                
  PV /dev/sdc1   VG VG01   lvm2 [149,05 GiB / 29,05 GiB free]
  PV /dev/sdb2   VG VG00   lvm2 [465,25 GiB / 19,25 GiB free]
  PV /dev/sda2   VG VG00   lvm2 [59,09 GiB / 35,09 GiB free]
  PV /dev/sdb1   VG VG00   lvm2 [480,00 MiB / 480,00 MiB free]
  Total: 4 [673,86 GiB] / in use: 4 [673,86 GiB] / in no VG: 0 [0   ]

Mais j'ai pa de pv0 ou pv2...

Une idée ?

LVM met quelques métadonnées en début de partition.
Est-ce des disques recyclés ? Auquel cas, ça pourrait expliquer.

llaumgui

Non, pas de recyclage...

llaumgui

Toujours pareil et mon boot s'en retrouve de plus en plus long...

et que donne un pvscan -vvv?
