In the course of time the size of data generated for gitlab-ci pipelines may grow quickly and sometimes reaches dozens of GB. The quantity of data stored on the gitlab's server for pipelines can be checked in the Settings -\> Usage Quotas panel of the project, or in Build -\> Artifacts. For projects with more than 10GB of artifacts there is certainly something to do to reduce the disk storage:
1) By cleaning old artifacts (cf https://gitlab.inria.fr/siteadmin/doc/-/wikis/faq#how-do-i-delete-the-oldest-or-most-recent-artefacts).
