Reduce repository size | error: failed to push some refs to [remote]-CodePudding

I am stuck for 2 days trying to find a way to clean up my remote gitlab repo. I mistakenly push local repo after adding my data folder, which I forgot to include in the git-ignore. Since then, I cannot push any more, as the remote grows to 9.8GB, so I kept getting exceeded storage error.

I then completely removed the data folder fom my git-tracked repo. The resulting local repo is now about 12M size (python scripts and jupyter notebooks) only. Despite this clean-up, yet I cannot push to remove.

I followed the procedure outlined here.

Cloned a fresh copy of my repository from using --bare and --mirror options:

$ git clone --bare --mirror my-repo.git

And changed to cloned repo:

$ cd my-repo.git

Purge all files larger than 10M:

$ git filter-repo --strip-blobs-bigger-than 10M
Processed 1306 blob sizes

Completely finished after 6.89 seconds.

Then delete this origin remote, and set the URL to my repository:

$ git remote remove origin
Note: A branch outside the refs/remotes/ hierarchy was not removed;
to delete it, use:
  git branch -d master
$ git remote add origin https://gitlab.com/my-repo.git

Now I need to force push my changes to overwrite all branches on GitLab:

$ git push origin --force 'refs/heads/*'

This step failed! Unfortunately, all answers to this and this didn't help solve the problem.

What do you suggest?

CodePudding user response：

A silly suggestion have you tried changing remote on gitLab and removing the folder to reduce the size of the repo? https://gitlab.com/gitlab-org/gitlab-foss/-/issues/3518

CodePudding user response：

remote: GitLab: You are not allowed to force push code to a protected branch on this project.

That's your answer, right there. You commanded GitLab to update the name master. GitLab said: "No. You are not allowed."

Find out who is allowed and have them do it, or change the set of people who are allowed, or authenticate as a person who is allowed. Those are your options.
