The directory is backed up to the Amazon S3 bucket. Whenever we try to run `git pull` that could pull in *large commits*, we are facing the following error. $ git pull origin main remote: Enumerating objects: 102, done. remote: Counting objects: 100% (102/102), done. remote: Compressing objects: 100% (101/101), done. remote: Total 102 (delta 1), reused 102 (delta 1), pack-reused 0 Receiving objects: 100% (102/102), 72.24 MiB | 15.48 MiB/s, done. Resolving deltas: 100% (1/1), completed with 1 local object. fatal: Failed to checksum '.git/objects/pack/tmp_pack_VvTvzo': No such file or directory fatal: fetch-pack: invalid index-pack output I can confirm that the file '.git/objects/pack/tmp_pack_XXXXX' is present once the command completes. In the S3 fuse logs, I see that the file is read before the file is created. The issue happens only during `git pull` and `git clone` with the large commits works without any issues. Can anyone help with any pointers/ workaround/ potential solution to fix this issue? Is there a way to override the location of temporary files "tmp_pack_XXXXX" files so that it can be created outside the mount directory? Setting the object directory outside the mount directory using GIT_OBJECT_DIRECTORY is not an option as we want to backup git history. P.S. My experiment that could throw some light on the issue. 1. Created a Git repository with 1000 files of 1 MB. (https://github.com/cyn0/2kfiles-large) 2. Git clone on the mounted directory works without any issue. 3. Added 5 files of each 1MB size to the repository. (https://github.com/cyn0/2kfiles-large/commit/42aa5d83e9035460ffa9c3b2f4494c0828f6b1c7) 4. From the mounted directory, "git pull origin main" works without any size. 5. Now, add 100 files of each 1MB to the repository. (https://github.com/cyn0/2kfiles-large/commit/7304886116d9bdec8a8c2da020776995a6624bd2) 6. From the mounted directory, "git pull origin main" fails with the above error. Thanks in advance for your help! Regards, Palaniappan ```
