Moving 10 repo's data into a newly mounted drive from their default location

Hello, my gitlab instance recently ran out of disk space. So I mounted another drive and went through the process of configuring it for gitlab. It worked fine as I can see both locations within my admin area.

The problem now is my drive is still full, and I have newly attached 1tb drive not being used.

I stopped the gitlab service and attempted to move a repo (/opt/gitlab/gitlab-data/repositories/my-group/my-repo) to the drive (mnt/drive/gitlab-data/repositories/my-group/my-repo) but heading into the repo within gitlab just said the repo is empty, so I moved the directory back and it was back.

How would I move, say 10, repos onto my new drive and tell gitlab that they’ve moved?
