# 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**

```shell
sudo gitlab-rake gitlab:env:info
```

**Source Installation**

```shell
bundle exec rake gitlab:env:info RAILS_ENV=production
```

Example output:

```

## Show GitLab license information **(STARTER ONLY)**

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/20501) in GitLab Starter 12.6.

This command shows information about your [GitLab license](../../user/admin_area/license.md) and
how many seats are used. It is only available on GitLab Enterprise
installations: a license cannot be installed into GitLab Community Edition.

These may be useful when raising tickets with Support, or for programmatically
checking your license parameters.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:license:info
```

**Source Installation**

```shell
bundle exec rake gitlab:license:info RAILS_ENV=production
```

Example output:

```plaintext
Today's Date: 2020-02-29
Current User Count: 30
Max Historical Count: 30
Max Users in License: 40
License valid from: 2019-11-29 to 2020-11-28
Email associated with license: user@example.com
```

## 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](../gitaly/index.md#run-gitaly-on-its-own-server).

You may also have a look at our troubleshooting guides for:

- [GitLab](../index.md#troubleshooting)
- [Omnibus GitLab](https://docs.gitlab.com/omnibus/README.html#troubleshooting)

To run `gitlab:check`, run:

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:check
```

**Source Installation**

```shell
bundle exec rake gitlab:check RAILS_ENV=production
```

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

Example output:

```plaintext
Checking Environment ...

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

Checking Environment ... Finished

Checking GitLab Shell ...

GitLab Shell version? ... OK (1.2.0)
Repo base directory exists? ... yes
Repo base directory is a symlink? ... no
Repo base owned by git:git? ... yes
Repo base access is drwxrws---? ... yes
post-receive hook up-to-date? ... yes
post-receive hooks in repos are links: ... yes

Checking GitLab Shell ... Finished

Checking Sidekiq ...

Checking Sidekiq ... Finished

GitLab config exists? ... yes
GitLab config outdated? ... no
Log directory writable? ... yes
Tmp directory writable? ... yes
Init script exists? ... yes
Init script up-to-date? ... yes
Redis version >= 2.0.0? ... yes

Checking GitLab ... Finished
```

## Rebuild authorized_keys file

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

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:shell:setup
```

**Source Installation**

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

Example output:

```plaintext
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**

```shell
sudo gitlab-rake cache:clear
```

**Source Installation**

```shell
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**

```shell
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**

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

**Source Installation**

```shell
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: **Warning:**
Don't run it while GitLab or Sidekiq is running

```shell
sudo gitlab-rake gitlab:exclusive_lease:clear
```

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

```shell
# 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](../../update/README.md#checking-for-background-migrations-before-upgrading)
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:

```shell
sudo gitlab-rake db:migrate:status
```

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

```shell
database: gitlabhq_production

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

## Run incomplete database migrations

Database migrations can be stuck in an incomplete state. That is, they'll have a `down`
status in the output of the `sudo gitlab-rake db:migrate:status` command.

To complete these migrations, use the following Rake task:

```shell
sudo gitlab-rake db:migrate
```

After the command completes, run `sudo gitlab-rake db:migrate:status` to check if all
migrations are completed (have an `up` status).

## 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](../../development/prometheus_metrics.md#update-existing-metrics), or as a [troubleshooting measure](../../operations/metrics/dashboards/index.md#troubleshooting).

To re-import the metrics you can run:

```shell
sudo gitlab-rake metrics:setup_common_metrics
```
