# 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](https://git-scm.com/docs/git-fsck)).
|
||
|
|
This step verifies the connectivity and validity of objects in the repository.
|
||
|
|
1. Check for `config.lock` in the repository directory.
|
||
|
|
1. 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
|
||
|
|
|
||
|
|
This task loops through all repositories on the GitLab server and runs the
|
||
|
|
3 integrity checks described previously.
|
||
|
|
|
||
|
|
```
|
||
|
|
# omnibus-gitlab
|
||
|
|
sudo gitlab-rake gitlab:repo:check
|
||
|
|
|
||
|
|
# installation from source
|
||
|
|
bundle exec rake gitlab:repo:check 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.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# omnibus-gitlab
|
||
|
|
sudo gitlab-rake gitlab:user:check_repos
|
||
|
|
sudo gitlab-rake gitlab:user:check_repos[<username>]
|
||
|
|
|
||
|
|
# installation from source
|
||
|
|
bundle exec rake gitlab:user:check_repos RAILS_ENV=production
|
||
|
|
bundle exec rake gitlab:user:check_repos[<username>] RAILS_ENV=production
|
||
|
|
```
|
||
|
|
|
||
|
