# Repository checks **(FREE SELF)**
|
|
|
|
You can use [`git fsck`](https://git-scm.com/docs/git-fsck) to verify the integrity of all data
|
|
committed to a repository. GitLab administrators can trigger this check for a project using the
|
|
GitLab UI:
|
|
|
|
1. On the top bar, select **Menu >** **{admin}** **Admin**.
|
|
1. On the left sidebar, select **Overview > Projects**.
|
|
1. Select the project to check.
|
|
1. In the **Repository check** section, select **Trigger repository check**.
|
|
|
|
The checks run asynchronously so it may take a few minutes before the check result is visible on the
|
|
project page in the Admin Area. If the checks fail, see [what to do](#what-to-do-if-a-check-failed).
|
|
|
|
This setting is off by default, because it can cause many false alarms.
|
|
|
|
## Enable periodic checks
|
|
|
|
Instead of checking repositories manually, GitLab can be configured to run the checks periodically:
|
|
|
|
1. On the top bar, select **Menu >** **{admin}** **Admin**.
|
|
1. On the left sidebar, select **Settings > Repository** (`/admin/application_settings/repository`).
|
|
1. Expand the **Repository maintenance** section.
|
|
1. Enable **Enable repository checks**.
|
|
|
|
When enabled, GitLab periodically runs a repository check on all project repositories and wiki
|
|
repositories to detect possible data corruption. A project is checked no more than once per month.
|
|
|
|
If any projects fail their repository checks, all GitLab administrators receive an email
|
|
notification of the situation. By default, this notification is sent out once a week at midnight at
|
|
the start of Sunday.
|
|
|
|
Repositories with known check failures can be found at
|
|
`/admin/projects?last_repository_check_failed=1`.
|
|
|
|
## What to do if a check failed
|
|
|
|
If a repository check fails, locate the error in the [`repocheck.log` file](logs.md#repochecklog) on
|
|
disk at:
|
|
|
|
- `/var/log/gitlab/gitlab-rails` for Omnibus GitLab installations.
|
|
- `/home/git/gitlab/log` for installations from source.
|
|
|
|
If periodic repository checks cause false alarms, you can clear all repository check states:
|
|
|
|
1. On the top bar, select **Menu >** **{admin}** **Admin**.
|
|
1. On the left sidebar, select **Settings > Repository** (`/admin/application_settings/repository`).
|
|
1. Expand the **Repository maintenance** section.
|
|
1. Select **Clear all repository checks**.
|
|
|
|
## Run a check using the command line
|
|
|
|
You can run [`git fsck`](https://git-scm.com/docs/git-fsck) using the command line on repositories
|
|
on [Gitaly servers](gitaly/index.md). To locate the repositories:
|
|
|
|
1. Go to the storage location for repositories. For Omnibus GitLab installations, repositories are
|
|
stored by default in the `/var/opt/gitlab/git-data/repositories` directory.
|
|
1. [Identify the subdirectory that contains the repository](repository_storage_types.md#from-project-name-to-hashed-path)
|
|
that you need to check.
|
|
|
|
To run a check (for example):
|
|
|
|
```shell
|
|
sudo /opt/gitlab/embedded/bin/git -C /var/opt/gitlab/git-data/repositories/@hashed/0b/91/0b91...f9.git fsck
|
|
```
|
|
|
|
You can also run [Rake tasks](raketasks/check.md#repository-integrity) for checking Git
|
|
repositories, which can be used to run `git fsck` against all repositories and generate repository
|
|
checksums, as a way to compare repositories on different servers.
