问题
Currently, we are forced to migrate our repository from Gitlab to Github. When we want to push our repo to Github with "git push -u origin master". Unfortunately, this results in the following errors (Copied Output 1):
remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com.
remote: error: File Data/Setup/Database.2.7.0.1.accdb is 426.50 MB; this exceeds GitHub Enterprise's file size limit of 200.00 MB
remote: error: File Data/DPM/Database 2.4.0.0.accdb is 422.12 MB; this exceeds GitHub Enterprise's file size limit of 200.00 MB
remote: error: File Data/Setup/Database 2.5.0.1.accdb is 422.00 MB; this exceeds GitHub Enterprise's file size limit of 200.00 MB
remote: error: File Data/Setup/Database 2.6.0.0.accdb is 421.98 MB; this exceeds GitHub Enterprise's file size limit of 200.00 MB
(and more ...)
It's insufficient to remove the file, because it is included in previous commits. We tried the following fix suggested in: https://medium.com/@mrkdsgn/fixing-the-gh001-large-files-detected-you-may-want-to-try-git-large-file-storage-43336b983272 . We tried to remove all the accessdatabases from our entire repo using the following command:
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch Data/\*accdb'
The output is as following (Copied Output 2):

It looks like we removed all files with .accdb extensions that appeared in the "exceed Github limit" error. But unfortunately, when we execute "git push -u origin master" again, we receive the same errors as in (Copied Output 1).
Does anyone have suggestions what we did wrong? How can we delete the accesdatabases in our repo?
PS. We tried the method as described in https://git-scm.com/book/en/v2/Git-Internals-Maintenance-and-Data-Recovery under "removing object" as well. The additional steps of garbage collect and git prune -expire now did not solve the problem.
回答1:
I guess the most likely problem is if you aren't filtering the entire history of master. The filter-branch command you gave will only filter the history of the current HEAD. If you're only going to push master, you could say
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch Data/\*accdb' -- master
Or, if you want to remove the file from the entire repo history, you could say
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch Data/\*accdb' -- --all
Keep in mind that before running another filter-branch command, you'll have to remove the original/ refs (if you haven't already). (These refs would also thwart attempts to clean up the local repo with gc, but I doubt that's really an issue. The pack sent to the server should only contain reachable objects... I don't know that the docs guarantee this behavior, but I don't think I've ever observed otherwise.)
If that still doesn't fix it, we may need more information. Make sure the error message is still exactly the same (not just the same general error, but maybe referring to other objects/paths, for example).
