• On the HeadNode of the cluster:

  • Stop the batch jobs with scancel <job_id>

• On the the CCME Management Host, you will need to perform the following steps. On each step, you can check the Compute Fleet status with pcluster describe-compute-fleet -n <cluster_name>:

  1. Stop the Compute Fleet with pcluster update-compute-fleet --status STOP_REQUESTED -n <cluster_name>, and wait for the Compute Fleet status to be stopped

  2. Update the cluster with pcluster update-cluster -c <configuration_file> -n <cluster_name>, and wait for the end of the cluster update

  3. Start again the Compute Fleet with pcluster update-compute-fleet --status START_REQUESTED -n <cluster_name>, and wait for the Compute Fleet status to be running

  4. Your cluster is now updated and functional
