Eu tenho uma caixa Debian com adicional (não é um disco de sistema) 1.5Tb sata hdd (wd caviar green). Existe apenas uma partição em todo o disco.
O disco é usado para backups do sistema remoto (com rsnapshot , a atualização de backup é executada a cada 4 horas) e o rtorrent para alguns arquivos. Então, o disco está permanentemente em uso.
Tudo estava perfeito, até que alguns erros do sistema de arquivos apareceram e eu não consegui excluir muitos arquivos devido ao erro de leitura / gravação do sistema de arquivos.
fsck me salvou, dentro de um mês erros ocorreram várias vezes. Toda vez que preciso desmontar a partição e executar fsck para corrigir todos os erros.
Durante fsck fs diferentes de leitura / gravação de blocos foram corrigidos, também apareceram algumas mensagens como:
Inode 61477311 ref count is 3, should be 2. Fix? yes
Block bitmap differences: -(246948483--246948494) -(246987843--246987871) -(246988756--246988758) -(246989103--246989109). Fix? yes
smartctl não mostra nenhum erro.
Então, eu devo fazer o backup de todos os dados e formatá-los, ou o disco está morrendo ou talvez haja outra maneira de corrigir o problema?
ps. Aqui está a saída do smartctls:
