在不中断 Windows 客户端负载的情况下重新启动 smbd 守护进程答案

【问题标题】：restart of the smbd daemon without interrupting the load on the windows client在不中断 Windows 客户端负载的情况下重新启动 smbd 守护进程

【问题描述】：

这样的问题，有一个使用smb的服务器（集群），服务器进入AD域，有时需要重启smbd服务（reload不合适），但同时在客户端（windows）上有一些文件的复制，然后加载被中断，点击“重试”按钮后，下载从头开始。是否可以做类似的事情，以便负载从中断的那一刻开始继续运行，也许您需要像这样配置客户端。客户端连接为 SMBv3 或 SMBv2

ubuntu 18.04 上的服务器。在 zfs 创建的 smb

【解决方案1】：

恢复复制操作不取决于 smb 客户端或服务器，而是取决于正在执行复制的应用程序。

标准 Windows 副本不知道恢复。

其他（第三方）应用程序（可能是Total Commander?）可以更智能。您甚至可以编写自己的应用来进行智能复制。
