[Résolu] Hardy incompatible avec LVM2 ???

Bonjour à tous,

Le problème que je rencontre se situe au niveau de la création du "Logical Volume", le lv donc.

root@thunder:~# lvcreate -L 10G -n lv1 volume1
  /proc/misc: No entry for device-mapper found
  Is device-mapper driver missing from kernel?
  Failure to communicate with kernel device-mapper driver.
  /proc/misc: No entry for device-mapper found
  Is device-mapper driver missing from kernel?
  Failure to communicate with kernel device-mapper driver.
  Incompatible libdevmapper 1.02.20 (2007-06-15)(compat) and kernel driver 
  striped: Required device-mapper target(s) not detected in your kernel
  lvcreate: Create a logical volume

Et pourtant tout semble bon.

Voici ma configuration:

[UPDATE]: J'ai trouvé la solution, le module dm-mod n'est pas chargé en mémoire, il suffit donc de faire un:

sudo modprobe dm-mod

et maintenant, j'obtiens bien:

root@thunder:~# lvcreate -L 367G -n lv1 volume1
  Logical volume "lv1" created
