git - 这个 git-LFS 损坏的文件错误是什么意思以及如何修复它？

Question

我不确定为什么，但我的 repo 协议(protocol)有点搞砸了，当我尝试将我的分支推送到 github 时，我收到一个错误:

> git push
Git LFS: (0 of 1 files) 0 B / 61.99 MB
LFS upload failed:
  (missing) path/to/bigfile (50...4b)
error: failed to push some refs to 'git@github.com:me/myproject'

> git-lfs ls-files
50.. - path/to/bigfile

>  git-lfs fsck
Object path/to/bigfile (50...4b) could not be checked: no such file or directory
Object path/to/bigfile (50...4b) could not be checked: no such file or directory
Moving corrupt objects to /Users/myname/.../.git/lfs/bad
rename /Users/myname/.../.git/lfs/objects/50/b6/50...4b 
/Users/myname/.../.git/lfs/bad/50...4b: no such file or directory  

请注意，我不关心删除或删除这个文件，它不再被使用。 (但文件在那里!) 我试过 git-lfs untrack path/to/bigfile 但没有成功，我无法推送我的分支。

如何解决这个问题？

修复损坏的 lfs 而不重写历史的方法:

# set origin to original repo
git remote set-url origin ssh://git@bitbucket.nl.xxx:7999/prod/A.git
git lfs update

# fetch lfs data from original repo
git lfs fetch --all origin

# set origin back to new repo
git remote set-url origin ssh://git@bitbucket.nl.xxx:7999/prod/B.git
git lfs update 

# get missing lfs data from new repo
git lfs fetch --all origin

# push missing lfs data in new repo
git lfs push –all origin

# final check
git clone ssh://git@bitbucket.nl.xxx:7999/prod/B.git
git lfs fetch --all origin
git lfs fsck
