I created a migration with a query that seems to have broken my migration. I added two groupBy on a query, instead of two orderBys. As a result, running drush mi MyMigration got stuck in what appeared to be an endless loop.

I CTRL-C'd the process and then ran a drush mst --all, but now the status is reporting as "Stopping" in the UI, and the drush ms command does not return.

I tried stoping and restarting MAMP, but to no effect.

Is there someway to force my migration to get unstuck?

  • There are many "migration" modules, please tell us exactly what you are using and how it is configured.

Did you try migrate-reset-status, and possibly with --force: https://www.drupal.org/node/1561820

Otherwise I typically restart PHP manually once (restart your webserver) and then use Drush to rollback all the migrations to try again fresh.


I rarely use the UI as everything is usable and scriptable via drush when using Migrate. And trying to use a webserver to check the status of long-running tasks can be error-prone.

  • I tried migrate-reset-status. It did allow me to rollback the migration - or at least appears to have. However, I still cannot get the status (drush ms status), and the UI shows that the migration is still stopping. I also restarted MAMP - and my desktop afterwards, to no affect. Not sure how to flush this state?

  • Try migrate-register. Again drush help migrate-register to see what it does. I recommend reading about every migrate command over a coffee: drush help --filter=migrate and then read the drush help COMMAND per command.

This worked for me:

drush php-eval "var_dump(Drupal::keyValue('migrate_status')->set('migration_id', 0));"
  • I'm unlucky, hasn't worked for me yet: set('migration_id', 0));" bash: -c: line 1: syntax error near unexpected token (' bash: -c: line 1: set -eu && ( /mnt/ddev_config/.global_commands/web/drush php-eval var_dump(Drupal::keyValue('migrate_status')->set('migration_id', 0));)' Mar 10 at 15:39
