我有 1 个盒子似乎不想运行 chef，而我还有另外 5 个使用相同 rhel 和 chef 版本的相同盒子，它们运行正常。在非工作盒子上，当运行手册为空时，Chef 可以正确运行，但当我向运行手册添加一些内容并重试时，Chef 会失败。
以下是返回的一些错误
/opt/chef/embedded/lib/ruby/2.6.0/fileutils.rb:529: [BUG] rb_sys_fail_path_in(rb_file_s_rename, (/tmp/chef-rest20230427-6900-1ip3kea, /var/chef/cache/cookbooks/selinux_policy/resources/fcontext.rb)) - errno == 0

我追踪到错误是由于 chef 尝试将文件从临时目录移动到其缓存目录：
例如：
从：/tmp/chef-rest20230427-6900-1ip3kea
到：/var/chef/cache/cookbooks/selinux_policy/resources/fcontext.rb
我可以以 root 身份通过终端/命令行移动文件，但是当我尝试使用 ruby 执行相同的更改时，出现相同的错误：
[root@myserver myuser]# /opt/chef/embedded/bin/irb
irb(main):001:0> require 'fileutils'

irb(main):002:0> FileUtils.mv('/tmp/chef-rest20230427-6900-1ip3kea', '/var/chef/cache/cookbooks/selinux_policy/resources/fcontext.rb')

当我使用 ruby 将文件移动到 /var/ 和 /var/chef/cache/cookbooks/s 目录时也会遇到错误。
话虽如此，当我在主目录中移动文件时，相同的 ruby 命令仍然有效
[root@mycomputer myuser]# /opt/chef/embedded/bin/irb
irb(main):001:0> require 'fileutils'
=> true
irb(main):002:0> FileUtils.mv('/home/myuser/fileIcreated.txt', '/home/myuser/chef-fileIcreated2.txt')
=> 0
我检查了我的工作服务器和非工作服务器之间的权限，它们看起来相同：notWorking：

我们在两个盒子上都安装了炭黑，但我在非工作盒子上禁用了它，但这并没有帮助，所以我不认为问题与炭黑有关。
此刻我已经没有主意了，有什么东西可以帮助我弄清楚这里发生了什么事？
谢谢，亚历克斯
答案1
我在澳大利亚一家大型组织工作，该组织也使用 Carbon Black，但我们的自动化套件使用的是 Puppet，而不是 Chef。我们看到的堆栈跟踪几乎与您在 Puppet 代理调用 FileUtils.mv() 时看到的相同。
调查显示，该问题实际上与 Carbon Black 有关，但并非由 b9daemon 进程引起。而是代理创建的内部内核挂钩。我们的测试显示，最新的 Carbon Black Linux 代理（截至撰写本文时为 8.7.14）的内核挂钩似乎存在故障，导致 Ruby 解释器崩溃。
我们通过完全关闭 carbon black（可以通过ps -ef | grep b9除 grep 命令之外没有任何输出来验证）、禁用 b9daemon 的 systemd 服务，然后重新启动服务器并尝试再次运行 puppet 来验证这一点。没有观察到进程崩溃。
此外，我们还将炭黑代理从 8.7.14 回滚到 8.7.8-16，发现问题不再发生。因此，您的其他机器可能安装了不同的炭黑版本，这可以解释为什么它们不受影响，而只有一台机器受到影响。
我们已经向 vmware 支持部门提交了一张票，vmware 工程师报告说，他们认为这个问题与他们已知的故障有关，他们正在尝试修复。一旦收到进一步的信息，我会更新此答案。
还应注意，该问题可能影响所有版本的 Linux，但我们只使用 RHEL 7 和 RHEL 8，因此我无法确认其他发行版是否受到影响。
TLDR：该问题是由于 Carbon Black 代理的特定版本 (8.7.14) 在内核挂钩中存在错误，导致 Ruby 解释器调用的底层 C 代码崩溃。回滚到代理版本 8.7.8-16 并重新启动是确认的修复方法，完全禁用代理 (不是只需将代理置于禁用策略中），然后重新启动系统。
更新：我们最近测试了 vmware 的测试版，并确认 Carbon Black 应用控制代理的测试版不再存在此问题。VMWare 表示修复将在下一个版本 (8.7.16) 中发布，该版本还将包括对 RHEL 8.8 的内核支持。此版本的发布日期暂定为 2-3 周后。

尝试在文件中将TMPDIR环境变量设置为/var/tmp/etc/chef/client.rb
例如将以下 ruby 代码添加到/etc/chef/client.rb
ENV['TMPDIR'] = '/var/tmp'
