[Résolu] Ecriture impossible sur disque partagé avec Windows
Bonjour à vous,
j'ai un petit problème, je dispose de plusieurs disques dur 1 SSD pour Windows et Linux, 1 HDD (stockage) pour mes documents et 1 deuxième HDD (sécurité) pour sauvegarder le premier.
Je réalise un montage du HDD de stockage en automatique au démarrage de l'ordinateur et partage dessus tous mes documents... Je n'avais pas de problème jusqu’à :
Sur Windows 10, j'ai mis en place l'historique des fichiers via le menu Démarrer > paramètres > mise à jour & sécurité> sauvegarde. Cette historique sauvegarde mes fichiers de mon premier HDD (stockage) sur le deuxième (sécurité).
Depuis, sous Linux, je n'ai plus les autorisations d'écriture sur le premier HDD (stockage), je peux consulté les documents mais pas les modifier.
Voici les permissions de mon disque :
doowy@LINUX-DOOWY:~$ ls -l /mnt/
total 40
drwxrwxrwx 1 root root 40960 juin 3 20:14 40F45DD6F45DCEB2
doowy@LINUX-DOOWY:~$J'ai essayé la commande suivante mais sans résultat.
doowy@LINUX-DOOWY:~$ sudo chown eweng /mnt/40F45DD6F45DCEB2
[sudo] Mot de passe de doowy :
chown: modification du propriétaire de '/mnt/40F45DD6F45DCEB2': Système de fichiers accessible en lecture seulement
doowy@LINUX-DOOWY:~$Est- il possible que je continue à utiliser ce disque en partage avec Windows ou suis-je obligé de désactiver l'historique des fichiers, ce que je préfère éviter?
Merci pour vos retours.

Bonjour
Peux-tu lancer windows.
Lorsque windows sera opérationnel,
https://docs.microsoft.com/fr-fr/troubl … ibernation
Appuyez sur Windows sur le clavier pour ouvrir le menu Démarrer ou l’écran de démarrage.
Recherchez cmd. Dans la liste des résultats de la recherche, cliquez avec le bouton droit sur Invite de commandes, puis sélectionnez Exécuter en tant qu’administrateur.
Lorsque vous y êtes invité par le contrôle de compte d’utilisateur, sélectionnez Continuer.
À l’invite de commandes,powercfg.exe /hibernate off
tapez, puis appuyez sur Entrée.
Tapez exit, puis appuyez sur Entrée pour fermer la fenêtre d’invite de commandes.
peux-tu l'arrêter en prenant l'option REDEMARRER.
Au redémarrage, choisis UBUNTU et vérifie si le problème persiste

En regardant ton boot-info, Je ne vois aucune raison qui empêche ubuntu de booter.
Il va falloir que tu expliques le problème.

=============================== StdErr Messages ================================
File descriptor 63 (pipe:[50933]) leaked on lvs invocation. Parent PID 4447: /bin/bash
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sdd5,
using the following options: sdd2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.2 LTS entry (sdd2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)1743 lignes, c'est commun ça comme longueur ?

Pas d'autres manip's récemment concernant les disques/partitions, le bios, ou les démarrages de l'un ou l'autre système ? Car il y a quand même une suggestion de réparation dans le boot-info :
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sdd5,
using the following options: sdd2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file …je ne sais pas ce qu'elle vaut.

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of sdd5, using the following options: sdd2/boot/efi, Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file…je ne sais pas ce qu'elle vaut.
Boot-info info indique toujours sa réparation préférentielle.....
même si tout fonctionne parfaitement bien.
On voit que c'est bien présent

Re : [Résolu] Ecriture impossible sur disque partagé avec Windows
Merci pour l'infos du démarrage rapide. Je ne savais pas que cela pouvait abimer les SSD
Non, ça n'est pas que ça abîme les disques ( peut-être ).
Le démarrage rapide façon Windows c'est un mix de mise en veille et d'hibernation : Windows fige les disques dans leur dernier état connu, en les « préemptant » en quelque sorte via leur passage en mode lecture seule, comme ça au démarrage suivant il reprend exactement dans-l-état-qu-on-l-avait-laissé. C'est plus rapide que de charger/compresser tout ça en RAM, puis au démarrage suivant décompresser/recharger l'état depuis la RAM ( ça, c'est l'hibernation ).
Du coup si le Windows est dans cet état « démarrage-rapide » on ne peut pas accéder à ses partitions depuis Linux, ou seulement en lecture seule à la rigueur.
Ça explique 50% de ta problématique initiale : la partition ntfs en lecture seule ( ton windows était probablement en attente d'un redémarrage rapide au lieu d'être vraiment éteint, les disques et partitions n'étaient pas libérés par cet OS ).
Ça n'explique pas pourquoi tu as perdu la possibilité de redémarrer Linux/Ubuntu. Quoi que : si le mode redémarrage rapide de Windows préempte aussi les partitions EFI nécessaires au boot, peut-être que ça peut gêner GRUB, geole un avis ? ( je pratique peu Windows. )
Reste cette question des options inhabituelles repérées via le boot-repair : quand tu installes Ubuntu, diverses questions sont posées, attention à ce qu'on coche ou décoche ? ? ? je dis ça à cause de ZFS qu'on peut activer durant l'installation il me semble ( c'est un genre de RAID ).
je venais juste de réinstaller WINDOWS et UBUNTU en mode EFI (précédemment en mode legacy)
Mmm… dans cet ordre là, ou tu as fini par l'install' de Windows ?
Tu as donc passé certains disques en table de partition GPT alors qu'ils étaient en MBR auparavant ?
en fait eweng était le profil de mon compte admin je voulais le garder secret mais bon tu m'a démasqué
Tant qu'on n'a pas accès physique à ta machine ou qu'on ne sait pas que ton mot de passe est gn3w3 tout va bien 
( euh si c'est vraiment ton mot de passe, promis, c'était de la pure supposition et change-le ).

@Coeur Noir : j'avais bien compris mais c'était un rappel général suite à ton message avec un mot de passe trop court.
Le problème, c'est que certaines personnes utilisent un mot de passe trop court ou trop simple, voire les 2.

Je rappelle que dans 100% des cas, il suffit de booter avec un support d'installation pour constater que le mot de passe seul ne sert strictement à rien. Il est donc totalement inutile de le compliquer. Un seul caractère est bien suffisant.

Bonjour Coeur Noir
Le boot-info ne n'a pas permis de comprendre pourquoi l'écran grub n'était pas proposé.
Il est vrai que chaque ordinateur EFI a ses particularités, Mais dans l'ensemble. On peut booter ubuntu
et si windows est en hibernation, les partitions NTFS sont maintenant montées en lecture seule,
Les partitions FAT32 ne sont pas incluses dans ce verrouillage.
Lorsque windows est rebooté par l'hibernation, les fichiers qui n'ont pas été fermés se retrouvent positionnés, Par exemple on peut continuer la modification de la 255éme page du document libre-office..
Pour le second plantage, la description est vraiment trop succincte pour avoir une piste avec la trace du plantage qui existe certainement....
"j'ai essayé, ça à planté UBUNTU. Je n'y ai plus accès du tous. J'ai remis en mode ON, mais je ne peux plus accéder à Linux!!!"

Depuis un disque mécanique, oui.
D'où la suggestion de geole d'installer Ubuntu sur un de tes SSD forcément plus rapide, ça pourrait descendre le boot en dessous des 30 secondes.

Re : [Résolu] Ecriture impossible sur disque partagé avec Windows
Merci pour vos réponses. Je suis désolé je ne suis pas à mon domicile jusqu'à jeudi soir. Je pourrais vous envoyer mon nouveau boot-infos dès le jeudi soir. Si vous pouviez me suggèrer des améliorations je suis preneur. Ce serait très gentil... Et oui je pense que le problème c'est que j'ai oublié de réformateur mon ssd avant de réinstaller (oublie un peu bête quand on ve repartir sur de bonnes bases). Qua'd au problème de démarrage de Ubuntu que j'ai eu, il s'agissait d'un bug au moment du chargement de Ubuntu. Le chargement semblait s'interrompre. Au début ça allait et après avoir choisi Ubuntu je bloquais au stade où l'image est celle où il est écrit Ubuntu et un rond tourne en dessous (ne tournais plus ?) . Après plus de 30 minutes d'attentes il ne se passai toujours rien. Je ne sais pas si j'ai été très clair.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sdd5,
using the following options: sdd2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.2 LTS CurrentSession entry (sdd2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)en fait je pensais que mon Ubuntu était installé sur le même SDD que windows. Durant l'instalation, j'aurais du réaliser les partitions moi même. J'ai laissé Ubuntu s'installé tout seul à côté de windoows je crois que mon erreur viens de la. Maintenant sur le disque sur lequel est installé Ubuntu, il n'était pas du tout prévu pour cela à l'origine (stockage uniquement). es-que je peut supprimer Ubuntu de ce disque et réagrandrir la partition de stockage pour qu'elle utilise l'ensemble du disque? Et ensuite réinstaller Ubuntu sur mon SDD ou windows est déja installé?
merci à vous.

Oui mais…
réagrandrir la partition de stockage
Oui mais…
…s'assurer :
⋅ d'une méthode propre pour enlever l'OS Ubuntu ET restaurer un démarrage conforme du PC.
⋅ sur sda, libérer un espace non alloué suffisant ( ±50 Go ) qui pourra accueillir Ubuntu ( la racine / complète du système ).
⋅ à l'installation d'Ubuntu bien viser cet espace non alloué sur sda comme destination, et bien placer le « chargeur d'amorçage » sur ce disque ( afin que GRUB te propose au démarrage les 2 OS ).
Je ne suis plus familier des installations avec Windows, donc la proposition qui suit est à valider par d'autres.
J'aurais sans doute utilisé os-uninstaller depuis une live-session pour virer Ubuntu → mais je ne sais plus ce que ça implique pour le redémarrage ensuite.
Car il faut que tu puisses redémarrer ton Windows, hein. C'est préférablement à partir de Windows qu'il faudrait « retailler » les partitions de sda afin de libérer suffisamment d'espace non alloué à destination de ton Ubuntu ensuite : ton sda de 240Go est actuellement complètement « occupé, couvert » par les partitions de l'installation Windows ( les partitions, ça ne signifie pas que « le disque » est rempli à 100% de données ).
En gros l'idée c'est de faire passer la partition sda3 de 223Go à par ex. 170Go. Pour pouvoir rétrécir cette partition, elle ne doit pas déjà contenir plus de 170Go de données, forcément contenu ≤ contenant. Donc probable ménage dans les données « Windows » à prévoir avant de t'attaquer à la partition elle-même.
Il faut rétrécir la partition correspondant au système Windows de sa fin à droite, vers la gauche, afin de créer l'espace non alloué à la suite, à droite. Autrement dit ne pas déplacer le début de la partition Windows ( sinon, se préparer à une réparation des démarrages ).
Quand on réalise cette réduction de partition immédiatement après l'install' du Windows, y'a de bonne chance qu'on puisse récupérer l'espace souhaité : les M.à.J n'y prennent pas encore trop de place, y'a pas de documents persos déjà stockés, le pagefile.sys n'est pas sollicité, on n'a pas une douzaine de points de restauration archivés et, comme évoqué, on aura déjà désactivé l'hibernation et le démarrage rapide. Désinstaller les logiciels inutiles, c'est bien aussi ( les versions démos de ceci ou cela qui prennent quelques Go sur la partition C:\ - Office, des jeux, des players multimédia et autres bloatware douteux ).
Quand on fait ça ( rétrécir la partition C:\ ) sur un système Win qui tourne depuis longtemps, il y a parfois des données que Win refuse de déplacer : il faut d'abord purger ses « archivages » ( concernant les M.à.J et restaurations ) et désactiver ( temporairement ) ces mécanismes. Et avant de redimensionner, impérativement défragmenter s'il s'agit d'un disque mécanique ( pas le cas ici, c'est un SSD ).
Et comme toujours quand on s'apprête à manipuler des partitions ( et ce quel que soit l'OS ) : s'assurer d'avoir une sauvegarde fiable de ses données précieuses, avoir sous le coude de quoi réinstaller les OS dans les ( rares ) cas les plus funestes.
Seulement quand tu auras constaté que la partition de Windows est bien rétrécie et que ton Windows est toujours fonctionnel, tu pourras installer Ubuntu dans l'espace non alloué précédemment libéré.
Ensuite on pourra parler « organisation de tes données » depuis Ubuntu : par ex. faire en sorte que les dossiers de ton répertoire perso « pointent » en fait des dossiers situées sur un de tes disques de stockage ? Voire même les dossiers que tu utilises déjà sous Windows dans ton répertoire perso là-bas ?

Re : [Résolu] Ecriture impossible sur disque partagé avec Windows
Merci beaucoup Cœur Noir, tes explications sont claires.
Je vais réaliser ce que tu viens de m'expliquer, et m'appliquer pour ne pas avoir à y revenir ultérieurement.
Je te souhaite une bonne continuation.

Re : [Résolu] Ecriture impossible sur disque partagé avec Windows
Euh… ouais dans le principe mais attends quand même confirmation sur la façon de supprimer Ubuntu et conserver un démarrage propre de ton pc, qui devra toujours te proposer au moins windows ou booter direct sur windows après suppression de l'Ubuntu « mal placée ».
C'est sur ce point précis que j'ai un doute.

Effectivement, je viens de tenter (débranché le HDD qui contenait Ubuntu) de voir si mon windows pouvait démarrer normalement sans Ubuntu, mais cela semble plus compliqué que prévu, windows ne se lance pas sans ce disque.
Je vais tenter de rechercher des informations sur la manière de procéder mais je ne sais pas trop quoi taper dans le moteur de recherche.

Re : [Résolu] Ecriture impossible sur disque partagé avec Windows
( dans les grandes lignes, hein ) L'installation d'Ubuntu a installé une autre amorceur de démarrage ( GRUB ). C'est alors lui qui est lancé par le bios ( au lieu du Windows Boot Manager initial ). Ce GRUB cherche des infos de boot qui sont sur chaque disque qui contient un OS. Et dans la partition dédiée au boot en cas d'installation UEFI. Tu enlèves un disque → GRUB ne trouve plus ses petits → pas de démarrage ( ou plus de propositions des divers OS ) → ça ne me paraît pas trop déconnant comme situation.
Tout rentre dans l'ordre quand tu remets le disque ?
Là ce que tu devrais chercher c'est : comment supprimer l'OS Ubuntu tout en conservant Windows fonctionnel ?
Tu as des pistes dans le §3 de la doc' d'os-uninstaller évoquée au #21 ( pas super simples ).
Sinon, pour contourner ou « retarder » la suppression de l'Ubuntu sur le DD mécanique, autre stratégie - si tu as la place :
⋅ faire le ménage dans Windows pour libérer ensuite un espace libre non alloué sur le SSD,
⋅ y faire là une nouvelle installation d'Ubuntu,
→ au démarrage tu te retrouveras alors avec 3 choix : 1 Win et 2 Ubu.
⋅ tu pourrais alors utiliser os-uninstaller depuis l'Ubuntu nouvellement installée, pour supprimer l'ancienne Ubuntu ( bien repérer qui est quoi au niveau des partitions mais au pire os-unistaller ne peut pas supprimer un OS en cours d'utilisation, donc risque faible ).
→ au démarrage suivant tu ne devrais plus avoir le choix qu'entre 2 OS : 1 Win et 1 Ubu, les 2 qui sont installés sur ton SSD.
( oui en fait c'est ça la méthode « simple » car ça conserve et « reconstruit » GRUB ou, au pire, il s'agira juste de réinstaller ou mettre à jour GRUB, c'est pas méchant, peut se faire depuis une live-session aussi ).
