一、背景

可能由於機器突然斷過電，或者系統問題。部署的Gitlab在某天執行時突然不正常，具體表現在通過瀏覽器進首頁時報錯（錯誤碼為500），訪問其中一個倉庫錯誤碼為503。如下：

後來發現無法備份，備份到某個倉庫的時候會終止。

查了一圈有人說是由於斷電導致某個檔案損壞了，繼而引發的問題。

版本：

系統：ubuntu16.04

GitLab版本：10.7.3

二、部分日誌：

備份時的日誌：（如下就是xxx_lib倉庫出了問題）

三、解決方法

0）先在本地把xxx_lib倉庫備份好。

/var/opt/gitlab/git-data/repositories/xxx_User/  （xxx_User為使用者名稱）

在此資料夾中把 xxx_lib.git  和 xxx_lib.wiki.git刪掉。類似於下面這樣，這兩個就是一個倉庫的資料。

 2）刪掉後，就可以通過瀏覽器訪問這個倉庫，只不過變成一個空倉庫了。

四、總結
