emergency mode
Bonjour,
Au démarrage de Ubuntu (V24.04 LTS) je rencontre l'erreur:
"You are in emergency mode. After logging in, type « journalctl -xb» to view system logs, « systemctl reboot » to reboot, « systemctl default » or « exit » to boot into default mode.
Appuyer sur Entrée pour la maintenance
(ou appuyer sur Ctrl et D pour continuer) "
J'ai tapé (comme j'ai trouvé indiqué sur le forum):
journalctl -b -p err
qui donne cette information que j'ai prise en photo:
root@h63: ** journalctl-b -p err
janv. 14 21:18:23 h63 kernel: x86/pu: VMX (outside TXT) disabled by BIOS
jan. 14 21:19:53 h69 systemd [1]: Timed out waiting for device dev-disk-by\x2duuid-70D6\x2d1701.device - /dev/disk/by-uuid/70D6-1701.
root@h63:#
Après Ubuntu démarre 'normalement'
Pour information j'ai exécuté le boot-info (c'est la 1ere fois), je suppose que cela vous donne les informations de mon systeme (sinon dites moi ce qu'il vous faut):
https://paste.ubuntu.com/p/pt4YKyNt2f/
Quelqu’un peut il m'aider?
Grand merci car je suis perdu.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of
sdd1 into the MBR of sdd.
Grub-efi would not be selected by default because no ESP detected.
Additional repair would be performed: unhide-bootmenu-10s
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sdd (ATA ST2000DM008-2FR1) disk!Conseils pour les nouveaux demandeurs et pas qu'eux

Re : emergency mode
Bonsoir.
Dans un de tes quatre /etc/fstab, tu as défini une partition de boot EFi qui n'existe plus.
dev/disk/by-uuid/70D6-1701
qui a disparu, il faut rectifier le fstsab en question.
Reste à lire le boot-info

Re : emergency mode
Bonjour Geole, et surtout Merci !!!
ça fait sacrement plaisir de voir quelqu’un qui vous entend et qui est compétent.
J'ai commenté la ligne du fstab.
Elle correspondait peut être à un disque dur qui contenait Apple/OSX. En effet c'est un hackintosh, assemblé par moi, avec 8 disques durs. Devant le problème j'ai débranché électriquement 4 disques et même une carte PCIe qui semblait avoir un problème?.
J'apprends, j'apprends : Je suis un jeune de 85 ans autodidacte en informatique !
Ma question maintenant est : était ce cette partition EFI qui causait tout le problème ??? (le journalctl contenait plein plein d'erreurs). Je soupçonnait même le Processeur??? Comment savoir que tout est correct maintenant?
Encore un énorme merci Geole, car j'y suis depuis dimanche à des heures avancées dans la nuit...
Est ce que ce soir je pourrai dormir tranquille?

Re : emergency mode
Bonjour
Cet incident provoquait le plantage en emergency. Mais le plantage en emergency peut avoir plein d'autres causes.
On peut toujours regarder si les anomalies de fonctionnement sont graves ou pas.

No Errors LoggedCela ne représente qu'un secteur physique et c'est le premier pour un disque statistiquement au milieu de sa vie. J'aurais aimé qu'il dise lesquels et quand cela est arrivé.
Pour le moment. Je dis "affaire à suivre". Tous les deux ou trois mois, tu feras cette commande pour savoir si cela empire ou pas. Car il possible que cette situation soit très ancienne.

Re : emergency mode
Merci Geole,
Ok je vais surveiller ce disque comme indiqué. Le système qu'y est n'est pas celui que j'utilise couramment.
Par contre, J'ai relancé boot info, et j'ai toujours le message :
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of
sdd1 into the MBR of sdd.
Grub-efi would not be selected by default because no ESP detected.
Additional repair would be performed: unhide-bootmenu-10sCela semble dire que grub2 n'est pas bien installé sur sdd (sur lequel est mob systeme principal que j'utilise en permanence).
Je ne suis pas à l'aise avec les grub, MBR, programme de démarrage, gpt, msdos...
- 1) Si je dois le faire comment je reinstalle le grub2 de sdd1 into the MBR of sdd?.
- 2) et que veut dire : unhide-bootmenu-10s
merci encore, car je suis soulagé que ce ne soit pas le processor (c'est à dire un gros problème de hard) et le disque dur sdc je peux le changer.

Re : emergency mode
Bonsoir.
Boot-repair a l'habitude de toujours proposer une réparation.
Même si le boot fonctionne bien.
Même si sa proposition est identique au boot actuel.
Il dit qu'il va laisser 10 secondes le menu grub affiché afin de te permettre de faire un choix.
Si au bout de 10 secondes tu n'as pas choisi, il fait un choix.
Cette réparation est forte utile lorsque initialement la valeur est de zéro seconde, cas assez fréquent. mais aucun intérêt pour toi puisque c'est 20 secondes.
