Bonjour,
En voulant faire la dernière mise a jour, j'ai du m'absenter quelques heures et en revenant j'avais un écran noir. J'ai voulu redemarrer et la => Symbole Sens interdit !
Je me destresse, je vais sur Mac Generation, je lis (entres autres l'excellent Macomaniac) et je tente la commande cmd+R au démmarage pour reinstaller MacOs. Le problème c'est que je ne peux pas selectionner de disque dur pour finaliser l'installation.
Je ne panique toujours pas, je retourne sur Mac Génération et je relis. J'ouvre l'utilitaire et je tape les commandes toujours demander par macomaniac au début. Voici ce que cela donne (j'ai supprimé tous les petits disques images du copié collé) :

Bloc de code:

Il me semble que ma situation est un peu différente de celles que j'ai déjà pu lire sur le forum. Cependant n'y connaissant pas non plus grand chose, je m'excuse d'avance si c'est une redite. Ma question est : Dois-je utiliser une commande de "formatage" de mon Disque dur et donc perdre mes données ?

Merci de votre aide!!
 
Bonjour Knight

Voici comment la partition-macOS du disque interne est décrite -->
Bloc de code:
   2:          Apple_CoreStorage HD                      749.3 GB   disk0s2

  • tu t'aperçois qu'elle est de type "Apple_CoreStorage". Càd. qu'elle héberge un dispositif qui virtualise un espace-disque secondaire > à partir d'un magasin de stockage dit "Physical Volume" inscrit dans la partition. La mention HD portée en regard du type : "Apple_CoreStorage" --> désigne le nom qui a été donné au dispositif CoreStorage d'ensemble (dit "Logical Volume Group") et possiblement aussi au volume terminal utilisable.
  • voici l'espace-disque virtualisé à partir de cette partition -->
Bloc de code:
/dev/disk2 (internal, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS                        +748.9 GB   disk2
                                 Logical Volume on disk0s2
                                 7B8ED8FA-4288-4430-B861-3F90506CB462
                                 Unencrypted

  • il s'agit d'un disque virtuel intitulé Logical Volume. On voit qu'il n'est pas chiffré par FileVault. Sur cet espace-disque virtuel > un système de fichiers jhfs+ (Mac OS étendu journalisé) --> forme le volume terminal dans lequel est installé l'OS. Mais aucun nom de volume (possiblement HD) ne se trouve mentionné sur le Logical Volume. La raison de cette absence reste à définir.

Passe la commande :
Bloc de code:
diskutil info disk2

  • qui affiche un tableau d'informations sur le Logical Volume et (éventuellement) sur le volume terminal hébergé.

Poste le retour.

Question : as-tu des données à récupérer dans le volume qui a disparu de l'affiche (possiblement intitulé HD) ?

   This disk is a Core Storage Logical Volume (LV).  Core Storage Information:

   Fusion Drive:             No
   Encrypted:                No

-bash-3.2#

A priori le disque n'est pas monté même si je ne comprend pas très bien ce que cela veut dire. Je vois qu'il n'y a pas d'espace disponible alors que j'ai très peu de chose sur mon Mac.

Pour répondre à ta question finale : Je n'ai rien d'irremplacable sur cet ordinateur heureusement. Donc on peut utiliser toutes les solutions et même le formatage.

PS : Je pars au travail et je ne pourrais pas répondre avant ce soir. Encore un grand MERCI.
 
D'accord : à ce soir !

- le volume terminal n'étant pas monté > la taille de son occupation ne peut pas être mesurée. D'où des réponses sans adéquation (genre : espace disponible = 0 ou volume non réinstallable). On verra si on peut récupérer le volume.​
 
Bonsoir Macomaniac,

Quand tu auras le temps, je suis prêt à suivre les procédures que tu voudra bien me donner. Aucune urgence, c’est quand tu peux !
 
Repasse une commande :
Bloc de code:
diskutil list

  • et poste le tableau des disques --> que je voie si les index n'ont pas changé.
 
Merci

Le système de stockage CoreStorage est sans erreur.

Le système de fichiers jhfs+ > formateur du volume --> a bien été trouvé. Mais il est corrompu (erreurs graves) au niveau du fichier spécifique du catalogue B-tree (qui gère les accès aux fichiers terminaux en lecture > édition > ajout > suppression).

Mais peut-être l'erreur somme toute basique (2 occurrences au lieu d'1 seule) --> est-elle réparable ? Passe la commande :

Le système de fichiers est irréparable -->

- veux-tu essayer de voir si le volume ne remonte pas dans un démarrage en mode Single User ? - ou bien es-tu partant pour un reformatage ?​

=> c'est une question de données à récupérer ou pas.
 
Macomaniac,

Merci beaucoup du temps que tu m'accorde. On peut essayer le Single User si tu veux bien. Après le formatage je m'y suis préparé ;°
