When performing an upgrade an additional 'gitlab-ctl restart' may be required for migrations to be in place

Summary

Customer performed an upgrade with downtime from 13.8.2 to 13.11.5 on their Geo primary. Users received 500 errors when attempting to create MRs with error ActiveModel::UnknownAttributeError (unknown attribute 'diff_type' for MergeRequestDiff.

This column was added with v13.9, but this migrations shows as up in gitlab-rake db:migrate:status:

up     20210107105306  Add diff type to merge request diffs

After executing gitlab-ctl restart the issue was resolved.

This is very similar to gitlab-org/charts/gitlab#2529 (closed).

Steps to reproduce

  1. apt-get install gitlab-ee=13.11.5
  2. gitlab-ctl reconfigure

This does not appear to happen consistently. This customer typically does zero-downtime upgrades, but did not do so in this case so they could jump multiple minor versions.

What is the current bug behavior?

Some actions may fail after upgrading if a manual gitlab-ctl restart is not executed.

What is the expected correct behavior?

No manual restart required when performing an upgrade.

Proposal

#6180 (comment 1074786793)

Locate areas of our documentation where we are documenting users manually run db:migrate or gitlab:db:configure, and ensure users know to restart puma and sidekiq processes.
