Purpose: We will be performing system maintenance on the cluster to install software on compute nodes and update configurations.
Impact: The cluster will be unavailable while the modifications are made and service restarts are performed on compute nodes.
Affected: This will affect the ability to run batch jobs on the cluster.
Outcome: Maintenance and configuration changes were completed without issue. Actual downtime during the procedure was 30 minutes. Services were restored at 6:30AM 11/18/2018.
