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.
config.lock
in the repository directory.refs/heads
.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.
remote: error: cannot lock ref
This task loops through all repositories on the GitLab server and runs the 3 integrity checks described previously.
Omnibus Installation
sudo gitlab-rake gitlab:repo:check
Source Installation
sudo -u git -H bundle exec rake gitlab:repo:check RAILS_ENV=production
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.
Omnibus Installation
sudo gitlab-rake gitlab:user:check_repos
sudo gitlab-rake gitlab:user:check_repos[<username>]
Source Installation
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
Example output:
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.
