chef-server-ctl 备份不遵守 --timeout答案

【问题标题】：chef-server-ctl backup not honoring --timeoutchef-server-ctl 备份不遵守 --timeout
【发布时间】：2017-06-14 05:06:53
【问题描述】：

尝试设置我们的厨师服务器的自动备份，但它在 tar 阶段超时。我手动运行了 tar，它似乎需要 20 多分钟，但默认超时是 10 分钟。我尝试使用 --timeout 并将其设置为 6000 之类的高值，但在 600 秒后仍然超时。

输出：

root@chef-server:/opt/opscode/embedded/lib/ruby/gems/2.1.0/gems/chef_backup-0.0.1# /usr/bin/chef-server-ctl backup --yes --timeout 60000

有什么想法吗？

编辑：

这是我认为创建 tar 的代码：

  def create_tarball
    log 'Creating backup tarball'
    cmd = [
      "tar -czf #{tmp_dir}/#{export_filename}",
      data_map.services.map { |_, v| v['data_dir'] }.compact.join(' '),
      data_map.configs.map { |_, v| v['data_dir'] }.compact.join(' '),
      Dir["#{tmp_dir}/*"].map { |f| File.basename(f) }.join(' ')
    ].join(' ').strip

    res = shell_out(cmd, cwd: tmp_dir)
    res
  end

【问题讨论】：

您能否包含执行tar 操作的相关执行语句/代码？
我必须深入研究厨师代码才能找到它。请耐心等待，我会看看我能不能找到它.. 更新原帖

【解决方案1】：

看起来 chef_backup/master/lib/chef_backup/helpers.rb 文件中的 shell_out 函数在 12.6.0 中已过时，并且未在 --timeout 设置中合并。我将文件替换为：https://raw.githubusercontent.com/chef/chef_backup/master/lib/chef_backup/helpers.rb，并且能够覆盖默认超时并允许完成备份。
