使用递归标志和正常操作时 Rsync 突然挂起
Rsync suddenly hanging when using recursive flag and on normal operations
我正在使用 rsync 将数据从 VPS 同步到通过 Wireguard 隧道连接的本地存储 NAS。
这几个月来一直运行良好，但几周前我注意到同步无法再完成。
我调查了一下，发现 rsync 在某些操作中刚开始挂起，最终因此超时。这是使用 -vvvrP 标志的 rsync 操作的日志：

它不会比这更进一步，永远挂在这一步。
但是，我发现如果删除 -r 标志，操作会成功完成。但显然这意味着并非所有数据都被 t运行 转发。 （同样适用于 -a 这意味着 -r）
我还注意到一个问题，当 t运行sferring 目标中已经存在但修改日期较早的单个文件时。除非我添加 -W 标志，否则 Rsync 也会在此操作中挂起。这使得单一操作有效，但对 t运行sferring 目录没有影响，其中包含许多文件和子目录。
我还想补充一点，这已经完美运行了几个月，我最近搬家了，所以目的地，我的本地 nas，现在位于不同的网络上。不过，我已经打开了所有相关端口并验证了 Wireguard 隧道是否正常工作。
编辑
本地 NAS 当前在 Fritz.Box 路由器网络上。我怀疑这可能是问题的一部分，因为这是唯一发生变化的事情，它以前在不同网络中的另一个 ISP 路由器上
我试过的
我尝试了几种不同的标志组合，包括 -t 和减少冗长都遇到了同样的问题。
我已经确认存在到目标 NAS 的连接并且我可以使用 rsync 通过隧道发送测试文件。
我已验证目标有足够的可用空间space并且分区和文件系统干净且健康
最后是 运行 操作的 strace 日志：https://pastebin.com/uZ3U75Es
编辑：
我刚刚验证了 rsync 操作在本地完美运行，所以问题一定出在网络中

我已经弄明白了，Tshark 给了我一个关于 TCP 重传错误的提示，在 google 上反向搜索发现 MTU 设置可能有问题，确实这就是问题所在，设置 MTU在 Wireguard 中正确解决了这个问题
我正在使用 rsync 将数据从 VPS 同步到通过 Wireguard 隧道连接的本地存储 NAS。
这几个月来一直运行良好，但几周前我注意到同步无法再完成。
我调查了一下，发现 rsync 在某些操作中刚开始挂起，最终因此超时。这是使用 -vvvrP 标志的 rsync 操作的日志：

它不会比这更进一步，永远挂在这一步。 但是，我发现如果删除 -r 标志，操作会成功完成。但显然这意味着并非所有数据都被 t运行 转发。 （同样适用于 -a 这意味着 -r）
我还注意到一个问题，当 t运行sferring 目标中已经存在但修改日期较早的单个文件时。除非我添加 -W 标志，否则 Rsync 也会在此操作中挂起。这使得单一操作有效，但对 t运行sferring 目录没有影响，其中包含许多文件和子目录。
我还想补充一点，这已经完美运行了几个月，我最近搬家了，所以目的地，我的本地 nas，现在位于不同的网络上。不过，我已经打开了所有相关端口并验证了 Wireguard 隧道是否正常工作。
编辑 本地 NAS 当前在 Fritz.Box 路由器网络上。我怀疑这可能是问题的一部分，因为这是唯一发生变化的事情，它以前在不同网络中的另一个 ISP 路由器上
我试过的
我尝试了几种不同的标志组合，包括 -t 和减少冗长都遇到了同样的问题。
我已经确认存在到目标 NAS 的连接并且我可以使用 rsync 通过隧道发送测试文件。
我已验证目标有足够的可用空间space并且分区和文件系统干净且健康
最后是 运行 操作的 strace 日志：https://pastebin.com/uZ3U75Es
编辑：
我刚刚验证了 rsync 操作在本地完美运行，所以问题一定出在网络中

我 运行 在目标设备上 Tshark 一次，发送一个已知可以工作的文件，一次发送使 rsync 挂起的文件夹：
