Pool stuck in "Resuming" status

Hi,

 

I recently made a change to the "Apache Airflow requirements" field to add two dbt packages. Ever since I made that change (over 18 hours ago) the pool has been stuck in "Resuming". I can't stop the pool or make any other changes to the project. This has rendered the entire job useless as the web UI is throwing a 503 error as well.

 

I tried to remove the two packages that I added. The Fabric UI say "Successfully Saved", but if I go back into the settings the packages are still there. I'm not sure what to do here because I can't stop the pool, I can't make changes to the environment, and I can't use the Airflow web UI.  

 

For additional context:

I am using the Git sync for files. The two packages I added were "dbt-sqlserver==1.8.4, dbt-core==1.8.8"

Hi  , 

Since you mentioned issues after adding dbt-sqlserver==1.8.4 and dbt-core==1.8.8, try removing these dependencies via the Fabric UI:

  • Go to Settings > Environment Configuration.
  • Under Apache Airflow Requirements, remove or update the problematic packages.
  • Save your changes and monitor if the pool resumes successfully

I'm facing the same error. My Airflow instance is not responding, and now stuck at 'resuming' state. I tried to switch off and on the Fabric capacity but nothing changed.

Hi @bregenold 

 

Here are a few steps you can try to resolve the problem:

You can restart the Airflow Scheduler and Web Server, sometimes, restarting these services can help clear up any stuck processes.

airflow scheduler --stop
airflow scheduler -D

airflow webserver --stop
airflow webserver -D

 

You can use these following command to monitor the log output of the web server in real time, understand the working status of the web server, as well as the operations performed by users through the web interface and possible error messages. These two commands are very useful when maintaining and troubleshooting Airflow services, as they can help you track the activities of your system in real-time.

   tail -f /path/to/airflow/logs/airflow-scheduler.log
   tail -f /path/to/airflow/logs/airflow-webserver.log

 

 

If it does not help, you can try to clear the Airflow Database, sometimes, clearing the metadata database can help resolve stuck states. Be cautious with this step as it can affect your DAG runs.

airflow db reset

This command is used to reset or rebuild Airflow's metadata database. It's important to use this command with caution, as it clears all metadata, including information about the DAG run status, task instances, variables, and so on. and recreate the database structure.

Hey, thanks for the reply. However, I don't believe that I can run any of those commands as I don't have access to the underlying resources. This is hosted in Fabric, so afaik I can't remote into the machine that is actually running the Airflow process.

 

If you can please provide instructions on how to remote into the actual resource that's running Airflow I can try out the commands you sent.
