Failing background migrations

Hi,

after upgrading gitlab-ce from 15.3.2 to 15.11.0 via RPM on RHEL8, I have two failing background migrations.

CopyColumnUsingBackgroundMigrationJob: ci_build_needs

CopyColumnUsingBackgroundMigrationJob: sent_notifications

Both are more or less failing with a similar error:

ERROR:  column \"id_convert_to_bigint\" of relation \"ci_build_needs\" does not exist\nLINE 1: ...db_config_name:main*/ UPDATE \"ci_build_needs\" SET \"id_conver...\n

I am not sure why the column id_convert_to_bigint never got created.
How would I go about fixing this though?

Thanks

Same problem with “sent_notifications” here after upgrade from 15.6.x to 15.11.x.

Could this change here be related? But that’s already merged?

Exactly the same problem after upgrade from 15.6 → 15.11.
The same failed migrations “ci_build_needs” and “sent_notifications” and the same error.

One of the most important questions - does it have any impact on the working processes?

Hi,

from what I have noticed is that the migrations got canceled due to the scan_file_path issue while upgrading to 15.11.0:

`Running handlers complete

Not sure if this is unique to our setup or if this failed for everyone.
Also not sure how to rerun the canceled migrations.

Thanks

Hi,

I tried to rerun a db-migration to create missing columns. That worked without errors but also didn’t create any missing column:
gitlab-rake db:migrate --trace

Your re-execution of the background-migration failed for me with the same error.

Hi,

I was able to create the missing columns by doing the following for the send_notifications for example:

• Edit 20230130175512_initialize_conversion_of_sent_notifications_to_bigint.rb in /opt/gitlab/embedded/service/gitlab-rails/db/migrate and comment the “def down”:

# frozen_string_literal: true

class InitializeConversionOfSentNotificationsToBigint < Gitlab::Database::Migration[2.1]
  disable_ddl_transaction!

  TABLE = :sent_notifications
  COLUMNS = %i[id]

  def up
    initialize_conversion_of_integer_to_bigint(TABLE, COLUMNS)
  end

#  def down
#    revert_initialize_conversion_of_integer_to_bigint(TABLE, COLUMNS)
#  end
end

• Run “gitlab-rake db:migrate:redo VERSION=20230130175512”
• Revert edit on the above file
• Check if the column was added correctly via gitlab-psql
• restart background migration

However I am not sure if it is a good idea to make changes like this.
I’d prefer to see an official way to fix this or a statement that this will be fixed in the next release.

Thanks
Kristian

Thank you, your suggestion helped solve the problem.

Thanks, the fix worked OK.

More info: Upgrade from 15.7.0 to 15.11.0.

Hi @KWM83 - we have just opened a bug issue regarding this problem as we are currently working through this with one of our customers Batched Background migrations fail on upgrade from 15.7.0 to 15.11.0 (#408835) · Issues · GitLab.org / GitLab · GitLab.

Any other details will be posted there when available.

Many thanks!

This fix gets rid of sent_notifications task but leaves ci_build_needs unfixed.
I needed to do similar steps for 20230130104819_initialize_conversion_of_ci_build_needs_to_bigint.rb file and redo 20230130104819 version of migration to get rid of 2nd stuck migration.

Wow, thanks a lot! Hope this solution will help me too
