我在 ubuntu 22.04 系统上运行 Plex 媒体服务器 (PMS)。PMS 库已经有一段时间没有更新了，最近我开始向收藏中添加一些电影。但我发现，在添加目录/文件几个小时后，它会从系统中删除，没有任何痕迹。它似乎没有被移动或存档 - 只是被删除了。
有问题的父目录是 /svr/PlexMedia/Movies。例如，我最近添加了这些，但它们在几个小时内就消失了。此后我重新添加了它们：
> find /svr/PlexMedia/Movies/Makin* -ls
195952644 4 drwxrwxr-x 2 dennis dennis 4096 Nov 30 05:10 /svr/PlexMedia/Movies/Making\ Dark\ Side\ of\ the\ Moon\ (2002)

我以 /svr/PlexMedia/Movies 作为监视文件夹来运行该脚本，果然，在我添加了几部电影大约一小时后，它们就被删除了：

（我希望日志中的时间可以帮助我通过 syslog 识别某些进程（我当时想也许是来自 cron 的某些东西；现在我很确定不是，因为在任何一小时后的 25 分钟内都没有什么不寻常的安排。）
因此，我希望找到一种方法来审计这些删除。我遇到了 auditd（我现在已经安装了它），并通过以下命令开始监控：
sudo auditctl -w /svr/PlexMedia/Movies/ -p rw -k var-run-pids
然后我创建并删除了一个文件：touch /svr/PlexMedia/Movies/me rm /svr/PlexMedia/Movies/me
果然，我得到了该事件的审计日志。

也许 auditd 可以帮我做这件事，但我不熟悉这个工具，所以无法做到……我不知道。在我进入另一个兔子洞之前，我想在这里问一下，是否有某种神奇的方法可以找出触发删除这些文件的脚本或事件。它似乎很有针对性——正如我所暗示的，这个库已经存在很久了，而且（我能确定的是）这个长期存在的库是完好无损的。但它似乎坚持不添加任何新内容（或者说，确实不会添加很长时间）。
有什么帮助吗？
