Emergency WSC & WCERES Clusters MaintenanceUPDATE: January 31, 2019 4:30pm
Yesterday, at 5:30pm, engineers completed work on the WSC cluster. The WCERES cluster had some more serious issues arise during the maintenance and was unable to return to service at that time. Today, as of 4:00pm, engineers have completed maintenance on WCERES and have returned the WCERES cluster back to normal service. All systems on both clusters have been returned to normal operations. Please report any issues to firstname.lastname@example.org

The WCERES and WSC Hadoop clusters will be unavailable beginning at Wednesday, January 30th, 2019 at 8:00am, for emergency maintenance. The cluster is expected to return to full production by Thursday, January 31st, 2019 at 4:00pm.
During this time, WCERES and WSC Hadoop will have critical security patches made to the operating system.
Any PBS jobs which request a walltime which would take them past Wednesday, January 30th, 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 Wednesday, January 30th, 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.
