Corrupted repository on GitLab server

Hi,

I’m using an on-premisse GitLab installation version 12.2.1 (fa2d61ef521) and one specific repository seems to be corrupted. Running ‘git clone’ or ‘git pull’ on it from remote results on the following error:

Cloning into ‘checkbook’…

How I can workaround on this issue?

Thanks.

I just found the solution.

First I needed to run fsck on my repo at server side to check what file was missing:

$ git fsck

Checking object directories: 100% (256/256), done.
Checking objects: 100% (2960/2960), done.
broken link from tree 6e8155b60cc0d5e135b474ae9baf05d281cf94b1
to blob 159828e44b9ee2b4940da5398c75d6353a6f1532
missing blob 159828e44b9ee2b4940da5398c75d6353a6f1532
Verifying commits in commit graph: 100% (123/123), done.

So the blob 159828e44b9ee2b4940da5398c75d6353a6f1532 was missing.

I had to use an backup and then the following commands on the repository backup to restore the missing blob:

git show 159828e44b9ee2b4940da5398c75d6353a6f1532 > /tmp/bkp git hash-object -w /tmp/bkp

And everything work as expected again.
