Scheduler Administration

The Fuzzball scheduler is responsible for placing and managing jobs on compute nodes in your cluster. As a cluster administrator, you can monitor and manage scheduler behavior through various administrative commands.

All scheduler administration operations require that a fuzzball context is set up and authorized like so:

$ fuzzball context create <context_name> <api_url> <oidc_server_url> <oidc_client_id>

$ fuzzball context login -u <admin_username> -p '<admin_password>'

1. Cordon nodes to prevent new workflow placement
   1. Allows running workflows to complete
2. Perform maintenance operations
3. Uncordon nodes to resume normal scheduling

• Monitor node utilization and availability
• Plan for cluster scaling operations
• Manage resource allocation across nodes
