Microsoft文件服务器升级后，Azure App Service未重新启动 [英] Azure App Service Didnt Restart After Microsoft File Server Upgrade

问题描述

上个星期四(1月23日)，我们的Azure应用服务中断了(所有部署插槽)

Last Thursday (23rd January) our Azure App Service went down (all deployment slots)

使用诊断和解决问题"调试功能并深入研究，我发现了此错误".

Using the "Diagnose and solve problems" debug feature and drilling down into it I discovered this error".

Platform(File Server Upgrade) Your application was recycled due to a file server upgrade. This event occurred multiple times during the day across multiple instances. These events cause a Storage Volume movement which may result in a restart of your application. If this restart event negatively impacts the availability of the application, enabling the Local Cache feature can help reduce dependency on storage file servers to some extent.

由于我们使用的文件系统不多，并且所有部署插槽都没有重新启动，所以我不相信这是问题所在.我们必须重新启动每个单独的部署插槽才能使它们重新启动.

As we don't use the file system much and all deployment slots didn't restart I am not convinced that this is the issue. We had to reboot each individual deployment slot to get them to come back up.

其他人是否经历过类似的事情并且使用本地缓存功能"确实解决了该问题吗?这是过去24个月来我们的网站由于意外事件而第一次关闭.

Has anyone else experienced something similar and did using the "Local Cache feature" actually resolve it? This is the first time in over 24 months our site has been down due to an unscheduled event.

谢谢.

推荐答案

我想重申一下，您的应用程序的部署使用文件系统.创建应用程序服务时，基础文件系统为

I want to reiterate that the deployment of your app uses the file system. When you create an app service, the underlying file system is mounted to a storage volume.

要回答您的问题，使用本地缓存可以帮助减轻基础卷的维护时间，因为您的应用会将/site 和/siteextensions 内容复制到VM实例在启动时.复制后，VM将指向其内容的个人副本".查看 https://docs.microsoft.com/zh-cn/azure/app-service/overview-local-cache 了解更多信息.

To answer your question, using Local Cache can help mitigate when the underlying volume is undergoing maintenance because your app will copy the /site and /siteextensions contents to the VM instance upon start up. Once copied, the VM will point to it's "personal copy" of contents. Check out https://docs.microsoft.com/en-us/azure/app-service/overview-local-cache for more information.

希望这会有所帮助，如果没有帮助，请通知我.

Hope this helps and let me know if it doesn't.
