Hello, i am trying to clean up my git lfs repo in order to submit some new model and keep the lfs storage reasonable. I tried to use git filter repo accordding to [从 Git Large File Storage 中删除文件 - GitHub 文档], but it seems that, though I delete every appearance of my model, but the storage is not freed, I wonder if i am doing things the right way.
You can try this “git lfs prune” it worked for us

hello, thank you for your reply! I am trying out prune out some LFS no longer referenced, using these command, indeed my local .git/lfs reduced from 55GB to 30GB, but remotely the storage didnt decrease, Could you please take a moment to help me figure out what exactly went wrong? Thank you.

+ 2d05ca1...adb7b57 master -> master (forced update)Hi, again, you can use a branch to push this 30 gb (git checkout -b develop) and then mark this branch as default (this in gitlab web), so when you git clone after this, you only copy this 30 gb. If you do not understand me, tell me and I explain you with more detail
Hi, thanks for your reply again! i think i found the reason why the gitlab remote storage wont shrink. I tried to do repo clean up after i pruned and push my repo, and it worked!, My repo storage decreased to 30GB, thank you for your patience and help~ 
you are very helpful~
