GitLab數據庫損壞，如何恢復？

Question

我的GitLab數據庫（MySQL InnoDB）已損壞（我的硬盤出了點問題），我的最后一次備份是在從6.8升級到6.8.1的過程中執行的

現在我想再次啟動GitLab，但是如果我嘗試使用

/home/git/gitlab/$ bundle exec rake gitlab:backup:restore RAILS_ENV=production

我得到：

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

這是因為MySQL未運行，但是如果我嘗試使用service mysql start來啟動它，它將失敗，這是日志：

如何恢復我的上一次備份而不丟失我的上一次提交？

根據MySQL日志

140616 3:28:26 [錯誤]無法打開mysql.plugin表。 請運行mysql_upgrade創建它。

您必須運行mysql_upgrade命令來升級MySQL模式
