[RESOLVIDO] Emergency mode: journalctl -xb, ao iniciar sistema

Linux
#1

E ai galera, tive um pequeno problema na minha tela, e acabei desligando o PC no botão. Dai quando fui ligar novamente. O sistema não esta conseguindo dar boot.

Sistema: Mint 19.3, com dual boot. Tenho um SSD que tem o windows + SWAP + raiz. No HD tenho a /home e o disco \D.

mensgem do erro:
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. Pressione ENTER para manutenção

[email protected]:~# journalctl -xb

encontrei este erro nos logs (em vermelho)
index

Tentei fazer algumas coisas, como alterar o arquivo fstab. Mudei UIDD para dev/sda6. Mudar as opções de errors=remount-ro, para defaults

Teitei rodar: fsck.ext4 /dev/sd6 , mas como a unidade estava montada, ele me voltava erro e abortava o processo.

Fiz entao um liveCD(USB) e rodando o mesmo comando, obtenho a mesma saida:
[email protected]:~# fsck.ext4 /dev/sda6 e2fsck 1.44.1 (24-Mar-2018) /dev/sda6 is mounted. e2fsck: Cannot continue, aborting.

Alguem tem alguma ideia de como posso estar resolvendo este problema?

#2

Já tentou rodar um fsck na partição

fsck /dev/sda6

É depois vê se funciona

1 curtida
#3

tentei já.

[email protected]:~# fsck /dev/sda6

fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
/dev/sda6 is mounted.
e2fsck: Cannot continue, aborting.`

ele não ta deixando pq ta montado a partição, só que eu estou em liveCD, não era pra isso acontecer, ate onde eu sei.

#4

Ok…

Talvez tenha que fazer através de uma imagem de alguma distribuição.

Vc pode tentar desmontar

umount /dev/sda6

Senão só através de uma imagem

Deu certo.

umount /dev/sda6

fsck /dev/sda6

dei um reboot e o sistema deu boot normal. Vlw pela ajuda!

Estou com problema semelhante, sou bastante leigo, não consegui decifrar a partir do que já foi postado aqui.

Tudo começou quando eu fui atualizar o LinuxMint 18.3 que uso numa partição e o Windows 10 em outra. O computador desligou durante a atualização. Quando iniciei apareceu isso:

Welcome to emergency mode! After loggin in, type ‘‘journalctl -xb’’ to view system logs, ‘‘systemctl reboot’’ to reboot, ‘‘systemctl default’’ to try again to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):

A minha SENHA que ele pede não tá funcionando aí.
Se aperto Control + D, ele tenta de novo, mas passa. Fica na mensagem.

Estou usando um LIVE USB (pendrive com a mesma versão linuxmint 18.3)

Na saida do journalctl -xb saiu vermelho essas linhas em negrito

mint mint # journalctl -xb
