Erreur "Pas de système de fichiers racine" lors de la préconfiguration

Le groupe de volumes et les volumes logiques ont été créés avec succès. J'ai passé presque deux jours à tester et à googler. Maintenant, je ne sais vraiment pas ce que je devrais essayer maintenant. Merci pour toute aide.

le problème était dans cette ligne:

  mountpoint { / } .              \

Ça devrait ressembler à ça:

  mountpoint{ / } .              \

L'espace entre mountpoint et { n'était pas supposé être là.

soupir...
