Gitlab 进首页报错500 Whoops。 访问仓库错误码503

一、背景

可能由于机器突然断过电，或者系统问题。部署的Gitlab在某天运行时突然不正常，具体表现在通过浏览器进首页时报错（错误码为500），访问其中一个仓库错误码为503。如下：

后来发现无法备份，备份到某个仓库的时候会终止。

查了一圈有人说是由于断电导致某个文件损坏了，继而引发的问题。

版本：

系统：ubuntu16.04

GitLab版本：10.7.3

二、部分日志：

备份时的日志：（如下就是xxx_lib仓库出了问题）

三、解决方法

0）先在本地把xxx_lib仓库备份好。

1）进入Gitlab的存放仓库的目录，找到指定的仓库清空。

/var/opt/gitlab/git-data/repositories/xxx_User/  （xxx_User为用户名）

在此文件夹中把 xxx_lib.git  和 xxx_lib.wiki.git删掉。类似于下面这样，这两个就是一个仓库的数据。

 2）删掉后，就可以通过浏览器访问这个仓库，只不过变成一个空仓库了。

四、总结

1）要定期备份。

2）存放代码的机器要可靠，包含不限于系统稳定性和电源稳定。
