Como remover um arquivo que pode ser visto, mas nenhum programa parece tocar?

Question

Estou tentando remover alguns backups obsoletos e, no fundo, encontrei um arquivo 'cifs3bee' que não consigo remover. (E como não consigo removê-lo, ele está impedindo a remoção de toda a árvore de diretórios que leva a ele.) Se eu executar ls -l , obtenho:

total 1
-rwxr-xr-x 1 jgw87 root 307 Oct 30  2014 cifs3bee

E se eu executar file cifs3bee às vezes recebo:

cifs3bee: writable, regular file, no read permission

mas às vezes eu recebo:

cifs3bee: ERROR: cannot open 'cifs3bee' (No such file or directory)

que é basicamente o mesmo erro que eu sempre obtenho se eu executo rm, chmod, lsattr, less, ou praticamente qualquer outro comando nele (mesmo se eu sudo para root). Eu até tentei ' echo "x" > cifs3bee ' e ainda recebo um erro No such file or directory , mesmo que ls continue a mostrar o arquivo e ' rm -rf ' no diretório pai falhe dizendo que o diretório não está vazio.

O que está acontecendo aqui e alguém sabe como lidar com isso? Eu nem sei como esse arquivo entrou no meu backup, já que o nome não corresponde ao padrão que eu configurei para quais arquivos capturar.

Edit: Desculpe, esqueci as especificações do sistema. Este sou eu executando o Linux Mint 17, trabalhando em um servidor remoto do Windows montado via Samba. (Eu não sei as especificações do servidor.)

Editar: eu corri strace head cifs3bee , com a seguinte saída:

Infelizmente, não sei interpretar isso. Alguma ajuda?

    

Answer 1

Primeiro, gostaria de saber se você pode ter um espaço (s) à direita no nome do arquivo. Teste digitando ls "cifs e depois a guia para concluir automaticamente (supondo que você esteja em uma caixa do Linux, o que é uma grande suposição, é claro). Se isso não der certo, tente remover o arquivo pelo seu inode .

Boa explicação de como fazer isso aqui: excluir / remover arquivos com o inode número

Destaques do processo incluem: Primeiro, obtenha o inode do arquivo: ls -il

Depois, com o inode na mão, tente remover o arquivo:

find . -inum [inode-number] -exec rm -i {} \;</b>

Você ainda pode me converter no arquivo em torno de sua partição. Tente afastá-lo. Mas parece que é um erro de disco ou sistema de arquivos. O próximo passo que eu faria seria fsck.

Além disso, tente 'strace echo "abcd" > file 'e descobre qual syscall realmente gera o erro como "no such file or directory" porque se não existir deve ser criado, então algo não existe como o interpretador bash ou diretório pai ou echo não é echo mas sim alias.

Outra possibilidade de que algo remova / restaure o arquivo para que você não tenha muita sorte e seja removido ao mesmo tempo recriado.

Outra possibilidade é que algo específico para o sistema de arquivos como os outros caras apontam corretamente que a presença de 'cifs' no nome do arquivo aponta para essa possibilidade.
