10.13 High Sierra macOs High Sierra fsroot tree is invalid

Je n'y comprends rien. D'après toute mon expérience > la commande est valide, pourtant.

Passe cette variante :
Bloc de code: 
diskutil resizeVolume disk0s3 300g jhfs+ SOS 0b
 
Non malheureusement cela ne fonctionne pas plus.
Barre de progression jusque 40% puis plantage.

C'est à taper la tête sur un mur.

L'action est-elle possible par utilitaire disque ?
 
Tu dois pouvoir faire pareil dans l'«Utilitaire de Disque».

Sinon > il doit falloir re-démarrer en coup et rebooter par internet via ⌘⌥R. J'ai l'impression qu'il a un plantage.
 
Ok je vais alors tenter un redémarrage et relancer les commande dans l'ordre jusqu'à en avoir une qui passe.

Pour utilitaire disque, je vais attendre encore un peu. Pas super secure (une erreur et vite arrivé)
 
Toujours pas. J'en passerais surement pas l'interface graphique sinon sur un DDE.

Je ne comprends rien à ce blocage du re-partitionnement. J'ai déjà passé d'innombrables fois ce type de commande sans problème.

Tu n'as pas un DDE avec de l'espace libre > et les bons paramètres (table GUID > format jhfs+ de volume) ?
 
Pareil je ne comprends pas, et je confirme, j'ai pu voir ça sur le forum, tu en as passés beaucoup.

J'ai un DDE au format NTFS avec quelques giga (pas loin de 200g) sur lequel on pourrais créer une table GUID avec partition au format JHFS+
 
Si tu n'as pas de données sur le DDE > tu l'attaches au Mac > diskutil list > tu postes le tableau.

La je te répond NON.
  • Il n'est pas possible de splitter le disque (tout en préservant les données) et créer une table GUID avec partition au format JHFS+ ?
  • Si trop compliqué ou risqué, je vois/j'essaye pour obtenir (demain) un DDE, sur lequel est installé macOS Maverick avec 70g dispo. On créra une parttiton pour acceuillir High-Sierra. Possible ?
 
La table de partition désignée par FDisk_partition_scheme = MBR. Elle interdit le re-partitionnement en mode "live" (non destructeur = re-dimensionnement de volumes) > ce quel que soit le format de système de fichiers de la partition-cible.

Il vaut mieux que tu attendes demain d'avoir un DDE "malléable".

DDE Avec macOS Maverick (je pense...) avec quelques giga dispo (pas loin de 90g) sur lequel on pourrais tenter un resize et créer une table GUID avec partition au format JHFS+ pour install de high Sierra. Tu en penses quoi ?
Dis moi, je suis prêt pour dérouler les actions...
 
Alors passe la commande :
Bloc de code: 
diskutil resizeVolume disk3s2 49g jhfs+ SOS 0b

  • qui réduit le volume WD_HD_OSX à 49 Go et crée un volume SOS de 80 Go environ.

=> on va bien voir si elle passe...
 
J'ai déjà lancer le resize en partant d'une des commande vue ensemble hier.

J'ai réduit le volume WD_HD_OSX à 55 Go ce qui laisse environ 75 Go

La commande à correctement était exécuté, et l'install de High Sierra validé.

Tu vas bien voir une fois ta session ouverte > si tu peux remonter le volume Crucial_SSD_OS.
 
Impossible de remonter le disque, impossible de le réparer, et erreur de "space" sur les containers.

Et maintenant Docteur, on fait quoi ?
 
On a fait tout ce qu'on pouvait et je pense qu'il n'y a plus rien à faire. Il y trop d'erreurs radicales dans le système de fichiers apfs générateur du volume > pour qu'il puisse être remonté.

Soit tu fais ton deuil des données du volume > soit tu tentes (mais c'est payant - dans les 100€) une récupération avec un logiciel de récupération de données.
