Check Rake Tasks
Even though Git is very resilient and tries to prevent data integrity issues, there are times when things go wrong. The following Rake tasks intend to help GitLab administrators diagnose problem repositories so they can be fixed.
There are 3 things that are checked to determine integrity.
- Git repository file system check (git fsck). This step verifies the connectivity and validity of objects in the repository.
- Check for
config.lockin the repository directory.
- Check for any branch/references lock files in
It's important to note that the existence of
config.lock or reference locks
alone do not necessarily indicate a problem. Lock files are routinely created
and removed as Git and GitLab perform operations on the repository. They serve
to prevent data integrity issues. However, if a Git operation is interrupted these
locks may not be cleaned up properly.
The following symptoms may indicate a problem with repository integrity. If users experience these symptoms you may use the rake tasks described below to determine exactly which repositories are causing the trouble.
- Receiving an error when trying to push code -
remote: error: cannot lock ref
- A 500 error when viewing the GitLab dashboard or when accessing a specific project.
Check all GitLab repositories
This task loops through all repositories on the GitLab server and runs the 3 integrity checks described previously.
sudo gitlab-rake gitlab:repo:check
sudo -u git -H bundle exec rake gitlab:repo:check RAILS_ENV=production
Check repositories for a specific user
This task checks all repositories that a specific user has access to. This is important because sometimes you know which user is experiencing trouble but you don't know which project might be the cause.
If the rake task is executed without brackets at the end, you will be prompted to enter a username.
sudo gitlab-rake gitlab:user:check_repos sudo gitlab-rake gitlab:user:check_repos[<username>]
sudo -u git -H bundle exec rake gitlab:user:check_repos RAILS_ENV=production sudo -u git -H bundle exec rake gitlab:user:check_repos[<username>] RAILS_ENV=production
The LDAP check Rake task will test the bind_dn and password credentials
(if configured) and will list a sample of LDAP users. This task is also
executed as part of the
gitlab:check task, but can run independently.
See LDAP Rake Tasks - LDAP Check for details.
