问题
There's a private gitlab server in my company, which is created by using the docker-compose file of sameersbn/docker-gitlab:10.5.6.
Today when I try to move the mounted volumes to a new disk, I accidentally created 2 sets of docker containers(sameersbn/gitlab:10.5.6, sameersbn/postgresql:9.6-2, and sameersbn/redis:2.8.4) that use the same disk volumes.
Then a moment later, someone in the company told me that his project at gitlab returns 404 error.
I've checked the PostgreSQL database and found that the project still exists in the database. I mean SELECT * FROM projects WHERE name ='<project_name>'; returns data.
If I create a new empty project with the same name, I got Name has already been taken error.
Are there any ways to fix this problem?
It looks like that something got nasty inside the database, which causes the project to return 404 error when visiting the webpage.
