Gitlab Backup Error: pack-objects died of signal 9

I have a repository that has 2 branches with a size of 3.5GB. Each branch is about 1.5GB (the .git is 700MB by itself).

This is the error:

Backup failed

[FAILED]

failed: /opt/gitlab/embedded/bin/git --git-dir=/mountdata/gitlab/git-data/repositories/my-Project/my-git.git bundle create /mountdata/gitlab/backups/repositories/my-Project/my-git.bundle --all

error: pack-objects died of signal 9

error: pack-objects died

Since my server only has 4G of memory, my assumption is that the backup code runs out of memory every time I do back up.

Is there any better way to backup? maybe one branch at a time to prevent running out of memory?

Currently, the command in my cron job is:

0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1         
15 04 * * 1-7  umask 0077; tar cfz /secret/gitlab/backups/$(date "+etc-gitlab-\%s.tgz") -C / etc/gitlab
Solution

  • I think your assumption is right. Possible solutions are

    1. Run git repack before backup
    2. Add more RAM
    3. Use tar directly instead of git bundle

    4. Update gitlab to the lastest version may also help (not sure)
