Cleanup

Remove garbage from filesystem. Important! Data loss!

Remove namespaces(dirs) from /home/git/repositories if they don't exist in GitLab database.

# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:dirs

# installation from source
bundle exec rake gitlab:cleanup:dirs RAILS_ENV=production

Rename repositories from /home/git/repositories if they don't exist in GitLab database. The repositories get a +orphaned+TIMESTAMP suffix so that they cannot block new repositories from being created.

# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:repos

# installation from source
bundle exec rake gitlab:cleanup:repos RAILS_ENV=production
