Maintenance Rake tasks (CORE ONLY)

GitLab provides Rake tasks for general maintenance.

Gather GitLab and system information

This command gathers information about your GitLab installation and the system it runs on. These may be useful when asking for help or reporting issues.

Omnibus Installation

sudo gitlab-rake gitlab:env:info

Source Installation

bundle exec rake gitlab:env:info RAILS_ENV=production

Example output:

Check GitLab configuration

The gitlab:check Rake task runs the following Rake tasks:

  • gitlab:gitlab_shell:check
  • gitlab:gitaly:check
  • gitlab:sidekiq:check
  • gitlab:app:check

It will check that each component was set up according to the installation guide and suggest fixes for issues found. This command must be run from your application server and will not work correctly on component servers like Gitaly.

To run gitlab:check, run:

Omnibus Installation

sudo gitlab-rake gitlab:check

Source Installation

bundle exec rake gitlab:check RAILS_ENV=production

NOTE: Note: Use SANITIZE=true for gitlab:check if you want to omit project names from the output.

Example output:

Checking Environment ...

Git configured for git user? ... yes
Has python2? ... yes
python2 is supported version? ... yes

Checking Environment ... Finished

Rebuild authorized_keys file

In some case it is necessary to rebuild the authorized_keys file. To do this, run:

Omnibus Installation

sudo gitlab-rake gitlab:shell:setup

Source Installation

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:shell:setup RAILS_ENV=production

Example output:

This will rebuild an authorized_keys file.
You will lose any data stored in authorized_keys file.
Do you want to continue (yes/no)? yes

Clear Redis cache

If for some reason the dashboard displays the wrong information, you might want to clear Redis' cache. To do this, run:

Omnibus Installation

sudo gitlab-rake cache:clear

Source Installation

cd /home/git/gitlab
sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production

Precompile the assets

Sometimes during version upgrades you might end up with some wrong CSS or missing some icons. In that case, try to precompile the assets again.

This only applies to source installations and does NOT apply to Omnibus packages.

Source Installation

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:assets:compile RAILS_ENV=production

For omnibus versions, the unoptimized assets (JavaScript, CSS) are frozen at the release of upstream GitLab. The omnibus version includes optimized versions of those assets. Unless you are modifying the JavaScript / CSS code on your production machine after installing the package, there should be no reason to redo rake gitlab:assets:compile on the production machine. If you suspect that assets have been corrupted, you should reinstall the omnibus package.

Check TCP connectivity to a remote site

Sometimes you need to know if your GitLab installation can connect to a TCP service on another machine - perhaps a PostgreSQL or HTTPS server. A Rake task is included to help you with this:

Omnibus Installation

sudo gitlab-rake gitlab:tcp_check[example.com,80]

Source Installation

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:tcp_check[example.com,80] RAILS_ENV=production

Clear exclusive lease (DANGER)

GitLab uses a shared lock mechanism: ExclusiveLease to prevent simultaneous operations in a shared resource. An example is running periodic garbage collection on repositories.

In very specific situations, a operation locked by an Exclusive Lease can fail without releasing the lock. If you can't wait for it to expire, you can run this task to manually clear it.

To clear all exclusive leases:

DANGER: DANGER: Don't run it while GitLab or Sidekiq is running

sudo gitlab-rake gitlab:exclusive_lease:clear

To specify a lease type or lease type + id, specify a scope:

# to clear all leases for repository garbage collection:
sudo gitlab-rake gitlab:exclusive_lease:clear[project_housekeeping:*]

# to clear a lease for repository garbage collection in a specific project: (id=4)
sudo gitlab-rake gitlab:exclusive_lease:clear[project_housekeeping:4]

Display status of database migrations

See the upgrade documentation for how to check that migrations are complete when upgrading GitLab.

To check the status of specific migrations, you can use the following Rake task:

sudo gitlab-rake db:migrate:status

This will output a table with a Status of up or down for each Migration ID.

database: gitlabhq_production

 Status   Migration ID    Migration Name
--------------------------------------------------
   up     migration_id    migration_name

Import common metrics

Sometimes you may need to re-import the common metrics that power the Metrics dashboards.

This could be as a result of updating existing metrics, or as a troubleshooting measure.

To re-import the metrics you can run:

sudo gitlab-rake metrics:setup_common_metrics
