克隆时网络驱动器上的 Git 存储库都显示相同的错误：“packfile 与索引不匹配”

Question

I've been trying to solve this for hours and I've had 0 luck. Apologies in advance, I'm fairly novice when it comes to Git.

I have a large amount of Git repositories on a network drive (R: drive). All of these repositories are clones of another repository with different changes made in each one.

For my work, I frequently need to clone 10+ of these repositories to my local machine (C: drive), so I thought I would make a batch script that would automate the process for me.

When I ran my batch script (which was essentially just 10+ git clone R:\\INSERT_REPO_HERE C:\\INSERT_DIRECTORY_HERE statements), the process took hours, but this was normal, as my connectivity to the R: drive was poor.

The issue:

I was looking into ways to speed up the cloning process, and had found advice to do the following:

git config --global pack.windowMemory "100m"
git config --global pack.SizeLimit "100m" 
git config --global pack.threads "1"
git config --global pack.window "0"
git config --global core.compression 0
git config --global core.bigfilethreshold 200K

So, I ran those commands on both R: and C: drive.

Now, whenever I clone any repo from the R: drive to my C: drive, I get the following error:

Cloning into 'C:\Users\games\Documents\BitBucket\Adapt topics\BU11\BU11.3\src\course\en'...
done.

fatal: unable to checkout working tree

and retry with 'git restore --source=HEAD :/'

I have tried --unset ting the global config I set, but it doesn't fix anything. As far as I can see, the repos on the R: drive still have all my files, so I haven't lost any data; but I can't seem to find a way to fix this issue, and re-creating every single repo on the R: drive would take me a very long time too.

Also, running git fsck --full gives this result, regardless of which repository I do it on:

I'm not even entirely sure what a "pack file" even is. Please, any help would be greatly appreciated!

EDIT: I don't know if this helps, but looking in the .git/objects/pack folder of each repository in the R: drive shows that the .pack file was last modified on the same day that I ran the git config commands:

Answer 1

Never store a Git repository on a networked or cloud-synced drive.

What, "never"? ¹

Yes, really, never . Why not? Because problems like the one you saw will occur. Just don't do it.

Answer 2

While not an answer to my original post, I have found a workaround that's appropriate for my specific situation. Basically, I just recreated each repository.

I went into each repository and deleted the ".git" file, then ran

git init
git add .
git commit -m 'PackFix'

This does mean I've now lost all Git commit history for these repositories, but thankfully (for my specific situation), this isn't a big issue.

To anyone reading this in the future, I'd say this thread is more a warning about running --global commands on a network drive (especially if you don't fully understand what they'll do).
