Emergency Halstead Cluster Maintenance
January 24, 2019 8:00am - 1:00pm
Outages and Maintenance
As of 1:00pm, engineers have completed maintenance and have returned the Halstead cluster back to normal service. All queues have been enabled and jobs have resumed scheduling. Please report any issues to firstname.lastname@example.org
The Halstead cluster will be unavailable beginning at Thursday, January 24th, 2019 at 8:00am, for emergency maintenance. The cluster is expected to return to full production by Thursday, January 24th, 2019 at 1:00pm.
During this time, Halstead will have critical security patches made to the operating system.
Any PBS jobs which request a walltime which would take them past Thursday, January 24th, 2019 at 8:00am will not start and will remain in the queue until after the maintenance is completed. Any jobs which are still running at Thursday, January 24th, 2019 at 8:00am will need to be terminated. Unfortunately, due to the critical security nature of the work, these patches cannot be postponed to allow for normal job completion.
