Bonjour :)

j'ai un problème de stockage avec mon macbook air, je suis sous mojave, je n'ai plus de place alors qu'il est quasiment vide. mon disk4 VM faisait 80go (pas normal), je l'ai supprimé puis recrée à l'aide de deux commandes dans le terminal trouvé sur un forum proposé par Macomaniac. Mon volume macintosh hd disk1 n'est que de 38,5gb ce n'est pas normal il devrait faire beaucoup plus.. merci beaucoup pour votre aide Merci à Macomaniac.

Bonjour sambllm

Il y a 38,5 Go de blocs occupés alloués au volume Macintosh HD. En regard > 34,3 Gi = 37 Go de fichiers catalogués. À 1,8 Go près --> je ne suis pas sûr qu'une enquête de détail s'impose.

Bref : avec 39 Go de blocs occupés (somme des tailles des 4 volumes : Macintosh HD et ses 3 auxiliaires) --> sur une capacité totale de 121 Go du Conteneur => il devrait y avoir 82 Go d'espace disponible. Or la commande df atteste ceci -->
Bloc de code:
Filesystem     Size    Used  Avail
/dev/disk1s1   121G    39G   926M

  • càd. 926 Mo seulement d'espace disponible.

Si tu as eu 80 Go d'occupation du volume VM (Virtual Memory : archivage de la RAM et des fichiers de swap) --> c'est que tu as dû avoir un swap monstreux pendant un moment (RAM insuffisante par rapport aux processus lancés). Or tu n'as plus que 24 Ko actuellement.

Tout dépend de la quantité actuelle de RAM et de ton usage logiciel. Mais swap ou pas --> la question de savoir ce qui sur-occupe le Conteneur reste ouverte...

La somme des taille des 4 volumes est actuellement de 38,4 Go + 99 Mo > + 517 Mo + 24 Ko = 39 Go. Pourtant cette mention -->
Bloc de code:

  • déclare que l'espace de blocs occupé par les 4 volumes = 120 Go. Il s'agit manifestement d'une inconsistance logique.

On va conjecturer une erreur massive de la part de spaceman (le gestionnaire de l'allocation des blocs de l'apfs). Passe la commande :

diskutil verifyVolume disk1

  • qui vérifie l'apfs

.... réitéré un nombre indéfini de fois ...

  • conjecture vérifiée : erreur du spaceman de l'apfs > en ce qui concerne l'occupation des blocs du volume Macintosh HD (main device : appareil principal). La raison de la sur-occupation est donc une erreur logicielle.
  • le plus simple consisterait à cloner le volume Macintosh HD (38 Go de fichiers réels et pas plus) => dans le volume d'un DDE USB. Démarrer sur le le clone. Supprimer l'apfs du disque interne. Le recréer. Cloner à rebours.

=> as-tu un DDE qui pourrait servir à cette opération ?
 
merci de m'accompagner dans cette procédure, j'ai un disque dur 2to et un d'un To, je dois le formater ou pas ?

je viens de le brancher, j'attends vos instructions :)

celui là (=> elements 1to) je peux le reformater si besoin

j'ai l'impression que le problème vient de parallels desktop, j'avais mon windows (plus de 200go) sur mon disque dur 2to my passeport for mac, j'ai désinstaller parallels desktop sur le mac, pensez vous que je devrais reformater my passeportformac 2to pour ne plus avoir de problème ?

On est sauvés : le 2è DDE a une table GPT et un volume jhfs+. Rien que 14 Go de données.

On devrait pouvoir repartitionner non destructivement > même si une partition Apple_Boot sans volume est inscrite juste en-dessous de la partition du volume Elements.

Passe la commande (copier-coller) :
Bloc de code:
diskutil resizeVolume disk2s2 900g jhfs+ Clone 0b ; diskutil list disk2

  • la commande rétrécit (non destrictivement) le volume Elements à 900 Go > et crée un 2è volume Clone de 98 Go en format jhfs+ > enfin réaffiche la configuration du seul DDE

Poste l'ensemble de l'affichage retourné.

Parfait : tout en est place.

Question : possèdes-tu déjà le logiciel de clonage Carbon Copy Cloner ? - ou faut-il que je t'indique comment télécharger sa démo gratuite (un mois) ?
