Removing git LFS

I had been using git LFS, but I didn’t really have a need. Still, I had pushed large amounts of data and now I have been told this:

This repository is over its data quota. Account responsible for LFS bandwidth should purchase more data packs to restore access.

So, I want to remove git lfs. I have tried following these instructions. When I followed those instructions and I try to push, this is what happens:

[kyle] ~/Documents/HoustonPM2.5 [master] $ git push

remote: Try to push them with 'git lfs push --all'.

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://github.com/K20shores/HoustonPM2.5.git'

How can I remove all of my LFS files and push to my repository again?

HI @K20shores :wave:

You can use git lfs migrate instead of filter branch or the BFG Repo Cleaner, to move the large file to Git Large File Storage.
For more information about the git lfs migrate command, see the Git LFS 2.2.0 release announcement.

Having done this, however, you will need to contact or direct support team to remove objects from our servers as that does not happen automatically.

Use our Contact Us form to start the ticket. If you don’t have access to direct support, I can create a request on your behalf, with your permission.
