Estou executando um Ubuntu Precise 12.04.4 LTS vm em um ESXi. De repente, o processo de inicialização começou a falhar com a seguinte mensagem:
/dev/mapper/luxsrv--vg-boot: 251/249856 files (6.4% non-contiguous), 168519/499712 blocks
mountall: fsck /boot [333] terminated with status 1
Também notei que antes dessas mensagens, havia uma mensagem "md0: tabela de partição desconhecida".
Eu fui para um snapshot anterior e comparei os resultados fstab, blkdid e fdisk -l reais e eles são idênticos, exceto pelo "... não contém uma tabela de partição válida" que aparece no snapshot de trabalho, então eles não devem ser motivo de preocupação.
Eu posso inicializar no modo de recuperação, fazer o login com o root e acessar todos os meus dados. Tudo isso deixou perplexo e gostaria de receber ajuda ou ideias sobre como resolver esse problema.
Obrigado Joe
