# GitLab Git LFS Administration
Documentation on how to use Git LFS are under [Managing large binary files with Git LFS doc](manage_large_binaries_with_git_lfs.md).
## Requirements
* Git LFS is supported in GitLab starting with version 8.2.
* Users need to install [Git LFS client](https://git-lfs.github.com) version 1.0.1 and up.
## Configuration
Git LFS objects can be large in size. By default, they are stored on the server GitLab is installed on.
There are two configuration options to help GitLab server administrators:
* Enabling/disabling Git LFS support
* Changing the location of LFS object storage
### Omnibus packages
In `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['lfs_enabled'] = false
gitlab_rails['lfs_storage_path'] = "/mnt/storage/lfs-objects"
```
### Installations from source
In `config/gitlab.yml`:
```yaml
lfs:
enabled: false
storage_path: /mnt/storage/lfs-objects
```
## Known limitations
* Currently, storing GitLab Git LFS objects on a non-local storage (like S3 buckets) is not supported
* Currently, removing LFS objects from GitLab Git LFS storage is not supported

Git LFS makes this simpler for the end user by removing the requirement to learn new commands.

## How it works
Git LFS client talks with the GitLab server over HTTPS. It uses HTTP Basic Authentication to authorize client requests.
Once the request is authorized, Git LFS client receives instructions from where to fetch or where to push the large file.
## Requirements
* Git LFS is supported in GitLab starting with version 8.2
* Git LFS [client](https://git-lfs.github.com) version 0.6.0 and up

* Git LFS v1 original API is not supported since it was deprecated early in LFS development
* When SSH is set as a remote, Git LFS objects still go through HTTPS
* Any Git LFS request will ask for HTTPS credentials to be provided so good Git credentials store is recommended
* Currently, storing GitLab Git LFS objects on a non-local storage (like S3 buckets) is not supported
* Git LFS always assumes HTTPS so if you have GitLab server on HTTP you will have to add the URL to Git config manually (see #troubleshooting-tips)

## Troubleshooting

There are a couple of reasons why this error can occur:
* Wrong version of LFS client used:
* You don't have permissions to access certain LFS object
Check if you have permissions to push to the project or fetch from the project.
Check the version of Git LFS on the client machine with `git lfs version`. Only version 0.6.0 and newer are supported.
* Project is not allowed to access the LFS object
* Project is using deprecated LFS API
LFS object you are trying to push to the project or fetch from the project is not available to the project anymore.
Probably the object was removed from the server.
Check the Git config of the project for traces of deprecated API with `git lfs -l`. If `batch = false` is set in the config, remove the line and try using Git LFS client newer than 0.6.0.
* Local git repository is using deprecated LFS API
### Invalid status for <url> : 501
When attempting to push a LFS object to a GitLab server that doesn't have Git LFS support enabled, server will return status `error 501`. Check with your GitLab administrator why Git LFS is not enabled on the server. See [Configuration section](#configuration) for instructions on how to enable LFS support.
Git LFS will log the failures into a log file.
To view this log file, while in project directory:
```bash
git lfs logs last
```
If the status `error 501` is shown, it is because:
* Git LFS support is not enabled on the GitLab server. Check with your GitLab administrator why Git LFS is not enabled on the server. See [LFS administration documentation](lfs_administration.md) for instructions on how to enable LFS support.
* Git LFS client version is not supported by GitLab server. Check your Git LFS version with `git lfs version`. Check the Git config of the project for traces of deprecated API with `git lfs -l`. If `batch = false` is set in the config, remove the line and try to update your Git LFS client. Only version 1.0.1 and newer are supported.
