Espaço em disco consumido e ausente

  • 772

Minha unidade raiz tem 143,9 GB de espaço. Tenho uma vbox vdi que 60GB e o sistema operacional, que deve ser mais 30GB... deixando-me 54GB de espaço livre.

Problema:
esta manhã, recebi aleatoriamente uma mensagem de erro "espaço em disco cheio" para minha unidade raiz.

Eu imediatamente apaguei alguns shows de logs antigos ... mas esse espaço consumido (não liberado) e ainda recebo o erro ...

Não consigo localizar 54 GB de espaço em disco.

Isto é:root@machine:/# lsblk

    Achei o problema... Outra "montagem fantasma"...

    Inicializei em uma sessão do LiveUSB e executei os comandos acima para verificar meu disco ... todos os comandos diziam que o disco estava "feliz", mas cheio.

    Ainda na sessão liveUSB, montei meu disco via nautilus, mas no terminal executei novamente

    O 49G /media/ubuntu/06ed954b-3750-49d3-b02d-43943788697f/media/user/external_drive foi impossível porque não o montei durante a sessão liveUSB.

    então eurm -rf /media/ubuntu/06ed954b-3750-49d3-b02d-43943788697f/media/user/external_drive

    e pronto!

    49 GB de espaço voltaram para mim e posso finalmente fazer algum trabalho de verdade.

    Portanto, parece haver dois tipos possíveis de "montagens fantasmas" após reinicializações forçadas não recomendadas.

    Uma montagem fantasma de "erro de caminho" que encontrei aqui e agora Uma montagem fantasma de "espaço em disco" (observe, nenhum dos meus scripts se apavorou ​​porque os caminhos para minha unidade externa como usuário normal e root estavam corretos, mesmo que o " montaria fantasma" existia)

    Na sessão liveUSB, o gparted e outros aplicativos agora confirmam meu espaço livre em disco.
