我有某种同步脚本，每天通过 rsync 将文件从生产服务器传输到 DR 服务器。
然而，几天以来，脚本似乎崩溃了。
它们正在运行多个实例，所以我将它们全部终止并重新启动该过程，但是，它似乎没有做任何事情。
当使用 strace 跟踪 PID 时，我可以看到它一遍又一遍地重新读取相同的数据。
包装器运行的命令是：
root 4052277 30.5 0.1 61540 19280 pts/0 S+ 11:00 8:32 /opt/csm/64-bit/deps/1.0.6/bin/rsync --archive --compress --recursive --rsh=/usr/bin/ssh -i /root/.ssh/id_rsa_drsync --rsync-path=/usr/bin/rsync --verbose /app/PWC/ xm3p7050vmo://app/PWC

当做strace -p4052277，我得到：

只是一次又一次地淹没同一个块（FS 大约是 150Gbytes）
我该如何调查为什么会这样？（以前它运行得很好）我无法重新启动机器，因为它正在生产中。
这可能与文件夹中的坏链接或任何内容有关？或与正在使用的文件有关？（查看正在运行的进程，显然没有正在使用的文件），我可以添加其他 RSYNC 选项来修复该问题吗？
谢谢你的提示，
答案1
我会尝试先验证 rsync 是否正常工作。创建一个包含源中几个文件的小型测试目录，然后将其与目标同步以查看它是否正常工作。还添加--stats --verbose选项。
我猜这可能与网络有关。你能验证一下是否存在网络问题吗？
答案2
看起来我的文件系统在执行 rsync 时增长到了 100%，这可能是它失败的原因！
我将尝试扩展它并再次重新运行该过程（我也遇到了 ssh 密钥错误）
