Hi,
Not sure if it will help, you can try this though:
gitlab-rake db:migrate
that might get them going again. I do remember seeing someone running specific migrations manually, there was a post on this forum about it. I’ll see if I can find it.
EDIT: could be this post: 500 Error and Internal Server Error - #11 by BenjaminLeibinger as there are examples here how to do each migrate task manually as per your list above.
Also, not sure which version it appeared in but you could go to your server for example https://gitlab.example.com/admin/background_migrations and see if it shows exactly which one. Usually you find that under Admin → Monitoring → Background Migrations
