Backup rake task failing following system upgrade

How to Use GitLab Upgrade
1

After upgrade the Debian host onto which I’ve installed gitlab-ce the backup rake task is now systematically failing. Here’s the output with tracing activated, I’m sure it’s something stupid that I’ve overlooked but I’m at a loss and would appreciate any help possible :

Hi.
What kernel do you use?
I have same problem. I dont know exactly what it is, but:
If I run my old OpenVZ container as LXC on modern debian 9 (last rep kernel) and made dist-upgrade from deb 7 to 9 then update 11.6.10 to 11.7.1 gitlab-ce it works fine.
If I run my same old OpenVZ container on old debian 7 (last rep kernel) I got same problem as you.

Newer-mind. I’ve fixed the problem just reboot server and that is it!

Self answer, running gitlab-ctl reconfigure solved the issue.
