我有一台运行 FreeBSD 内核的 Debian 备份服务器和一台 ZFS 文件系统，我使用 ZFS 的快照和压缩技术将备份存储在该文件系统上。Debian 服务器rsync通过 cron 作业从多台其他服务器提取文件。这个过程非常有效。
然后，我使用 CIFS 将备份共享回原始服务器，这样我就可以轻松浏览它们并从每个服务器恢复文件。但是，当我ls在服务器上使用查看备份共享（通过 CIFS 安装）上某些目录的内容时，我看到多次列出了相同的文件。事实上，很多次：

这可能是什么原因造成的？我该如何解决？我并不依赖 CIFS，因此如果有更好的技术，我愿意接受。当备份服务器是 Open Solaris 时，我以前使用过 NFS，但 Debian 似乎在使用 FreeBSD 内核时不支持 NFS...
答案1
你正在经历Samba 错误 4715，报告为Debian 错误 #612503directory name cache size = 0。目前建议的修复方法是在 的全局部分下添加smb.conf。
