测试还原 - 不起作用

[Crius]

你好，你最喜欢的 bug 查找者、来打扰支持的用户又来了。

我今天下午在测试恢复时，两次都遇到了这个问题：

特别提一下

这让我有点想笑
我觉得这非常糟糕，从“还好”到“极其糟糕”的尺度上来说。

我在一个暂存环境（我们用于测试和随意摆弄的独立虚拟机）中进行了恢复，在执行了干净的：

• launcher stop app
• rm -rf /var/discourse/shared
• launcher rebuild app

之后。我尝试恢复的是自动化恢复创建的最后一个备份，并备份在 S3 中。
然后通过邮件提供的链接下载，并按照此指南进行恢复：

备份文件是 10GB。在 VM 上，当我开始恢复时，大约有 110GB 的可用空间。

您的磁盘空间不足。请确保此服务器上的可用空间至少是备份大小的 3 倍。

不。这是一个“提示”，意思是“这是一个常见问题”。

正如你回复的上一条帖子所述：

备份是 10GB。当我开始恢复时，虚拟机大约有 110GB 的可用空间。

（编辑了带有 GB 图像的版本，以便阅读）

进一步调查后，似乎备份的数据有问题，文件已损坏，或者烹饪过程弄乱了某些东西。

我将尝试下载另一个备份，看看备份文件之间是否存在相同的问题，以排除文件下载过程中出现问题的可能性。

更奇怪的是，加载该主题和该消息对于 discourse 来说根本没有任何问题。它加载并呈现都没有问题。

我已经手动干预并编辑了该帖子。现在正在启动手动备份以再次进行测试。
