Por que meu compartilhamento CIFS mostra os mesmos arquivos várias vezes?

3

Eu tenho um servidor de backup Debian rodando o kernel do FreeBSD e um sistema de arquivos ZFS no qual eu armazeno backups, usando as tecnologias de captura instantânea e compactação do ZFS. O servidor Debian usa rsync para extrair arquivos de vários outros servidores através de uma tarefa cron. Esse processo funciona muito bem.

Eu, então, uso o CIFS para compartilhar os backups de volta aos servidores originais, para que eu possa navegar facilmente neles e restaurar arquivos de cada servidor. No entanto, quando uso ls nos servidores para examinar o conteúdo de determinados diretórios no compartilhamento de backup (montado via CIFS), vejo os mesmos arquivos exatos listados várias vezes. Muitas e muitas vezes, de fato:

Mas no servidor de backup do Debian, parece bem:

O que poderia estar causando isso e como posso resolvê-lo? Eu não estou ligado ao CIFS, então se houver uma tecnologia melhor, eu estou aberto a ela. Eu estava usando o NFS antes, quando o servidor de backup era o Open Solaris, mas parece que o Debian não suporta o NFS ao usar o kernel do FreeBSD ...

Você está enfrentando o erro do Samba 4715 , informado como Bebê da África # 612503 . Atualmente, a correção recomendada é adicionar directory name cache size = 0 na seção global em smb.conf .
