Problem to solve

We need a method to batch move repositories to a new storage location

Target audience

• Storage Administrators
• Repo Administrators
• GitLab Instance Administrators

Further details

• Sometimes an instance for which GitLab runs may run low on storage (repos have grown)
• Sometimes an instance for which GitLab runs on may have an issue with it's underlying storage invisible to GitLab (disk corruption)
• Sometimes a smooth migration between GitLab instances have the ability to share a storage backend (nfs/ceph/etc)

Proposal

• Create a rake task that allows one to target an in use storage location for repos, and choose X method to move them to a targeted storage location.

What does success look like, and how can we measure that?

When we can easily migrate storage of repositories without downtime to GitLab itself.
