There are times when you need to perform maintenance work on a Maia runner, such as upgrading the version or updating the configuration to add new drivers, but you have running pipelines that you can’t allow to fail. In these cases, you can pause the Maia runner, which gracefully puts it into a safe state to be worked on. Pausing a Maia runner will allow it to finish outstanding pipeline tasks before entering a Paused state. Any running or submitted pipelines destined for the Maia runner during this Paused state will still be shown as active, and any new tasks from those pipelines will be safely queued until the Maia runner is resumed after the Paused state. While the Maia runner is paused, Maia users can continue to interact with the pipeline canvas in Designer.

​
Pausing a Maia runner

  1. On the Runners list, locate the Maia runner you want to pause and click the three dots ….
  2. Click Pause runner.
  3. Type pause runner in the dialog, to confirm you understand the implications of the action, and then click Pause Runner again.
When paused, the Maia runner first enters a Pausing state, during which it will complete any pipeline tasks it’s currently executing. Once those tasks are completed, it moves to a Paused state and any queued tasks will be held in the queue until the Maia runner is resumed. If tasks are executing within a Transaction, the entire transaction will complete before the Maia runner enters a Paused state.
To be clear: it is individual tasks in progress that are completed, not the entire running pipeline. The pipeline will not progress any further until the Maia runner resumes and its remaining queued tasks can be executed. The pipeline duration shown in the Pipeline run history will include any time that the pipeline spent waiting for a paused Maia runner to resume.

​
Restarting a paused Maia runner

When paused, the Maia runner can be safely restarted on the cloud provider, as described in Restart a Maia runner.
When a paused Maia runner is restarted on the cloud provider, the Maia runner status will remain Paused until the queue automatically resumes or you manually resume the Maia runner, as described below.

​
Resuming a paused Maia runner

  1. On the Runners list, locate the Maia runner you want to resume and click the three dots ….
  2. Click Resume runner.
  3. Click Yes resume to confirm.
If a Maia runner is left in a Paused state for 12 hours, it will automatically resume. A resumed Maia runner‘s status will be as follows:
  • If the Maia runner is actively connected and available, the resumed Maia runner status will be Running and it will begin to execute queued tasks.
  • If the Maia runner was stopped during the pause and was never restarted, the resumed Maia runner status will be Stopped.
  • If the Maia runner was taken offline, not gracefully stopped during the pause, and never restarted, the resumed Maia runner status will be Unknown.
If a resumed Maia runner is not in a running state, then any pipelines that had tasks queued during the pause will time out after 15 minutes of the Maia runner resuming, and the pipelines affected will be updated accordingly.
