# Cleanup
## Remove garbage from filesystem
DANGER: **Danger:**
The commands below will remove data permanently from your GitLab instance. Only use
these commands if you are 100% certain that it is safe to delete this data.
Remove namespaces(dirs) from all repository storage paths if they don't exist in GitLab database.
```
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:dirs
# installation from source
bundle exec rake gitlab:cleanup:dirs RAILS_ENV=production
```
DANGER: **Danger:**
The following task does not currently work as expected.
The use will probably mark more existing repositories as orphaned.
For more information, see the [issue](https://gitlab.com/gitlab-org/gitlab/issues/24633).
Rename repositories from all repository storage paths if they don't exist in GitLab database.
The repositories get a `+orphaned+TIMESTAMP` suffix so that they cannot block new repositories from being created.
```
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:repos
# installation from source
bundle exec rake gitlab:cleanup:repos RAILS_ENV=production
```
Remove old repository copies from repositories moved to another storage.
```
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:moved
# installation from source
bundle exec rake gitlab:cleanup:moved RAILS_ENV=production
```
Clean up local project upload files if they don't exist in GitLab database. The
task attempts to fix the file if it can find its project, otherwise it moves the
file to a lost and found directory.
```
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:project_uploads
# installation from source
bundle exec rake gitlab:cleanup:project_uploads RAILS_ENV=production
```
Example output:
```
$ sudo gitlab-rake gitlab:cleanup:project_uploads

## Remove orphan artifact files
When you notice there are more job artifacts files on disk than there
should be, you can run:
```shell
gitlab-rake gitlab:cleanup:orphan_job_artifact_files
```
This command:
- Scans through the entire artifacts folder.
- Checks which files still have a record in the database.
- If no database record is found, the file is deleted from disk.
By default, this task does not delete anything but shows what it can
delete. Run the command with `DRY_RUN=false` if you actually want to
delete the files:
```shell
gitlab-rake gitlab:cleanup:orphan_job_artifact_files DRY_RUN=false
```
You can also limit the number of files to delete with `LIMIT`:
```shell
gitlab-rake gitlab:cleanup:orphan_job_artifact_files LIMIT=100`
```
This will only delete up to 100 files from disk. You can use this to
delete a small set for testing purposes.
If you provide `DEBUG=1`, you'll see the full path of every file that
is detected as being an orphan.
If `ionice` is installed, the tasks uses it to ensure the command is
not causing too much load on the disk. You can configure the niceness
level with `NICENESS`. Below are the valid levels, but consult
`man 1 ionice` to be sure.
- `0` or `None`
- `1` or `Realtime`
- `2` or `Best-effort` (default)
- `3` or `Idle`
## Remove expired ActiveSession lookup keys
```
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:sessions:active_sessions_lookup_keys
# installation from source
bundle exec rake gitlab:cleanup:sessions:active_sessions_lookup_keys RAILS_ENV=production
```
