How to shrink my Gitlab repo history?

I have a repo on Gitlab Cryptocurrency Historical Data which I use to store large .csv files in the data dir. However the git history was getting to large for my Gitlab limit (10 GB). I removed the data in hopes of making my repo smaller. However Gitlab is still showing that the repo is taking up 9.5GB. How do I get rid of the git history for the repo?

I’ve tried using bfg-repo-cleaner similar to solutions provided by similar questions, however it only cleans the local repo and does not clear the history on Gitlab.

My question is how do I clean Gitlab’s history?

any feedback on this issue?


Does following the git filter-repo and repository cleanup instructions on Reduce repository size | GitLab help?
