Check Rake Tasks

Repository Integrity

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.

  1. Git repository file system check (git fsck). This step verifies the connectivity and validity of objects in the repository.
  2. Check for config.lock in the repository directory.
  3. Check for any branch/references lock files in 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.

  • 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

Note:

  • gitlab:repo:check has been deprecated in favor of gitlab:git:fsck
  • Deprecated in GitLab 10.4.
  • gitlab:repo:check will be removed in the future. Removal issue

This task loops through all repositories on the GitLab server and runs the 3 integrity checks described previously.

Omnibus Installation

sudo gitlab-rake gitlab:git:fsck

Source Installation

sudo -u git -H bundle exec rake gitlab:git:fsck 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.

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:

gitlab:user:check_repos output

LDAP Check

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.
