REVISED: System maintenance scheduled for Tuesday, December 11

December 11, 2018

CISL system administrators were able to install a new version of PBS during an unscheduled Cheyenne outage on Tuesday, December 4, so no Cheyenne downtime is needed during the maintenance period scheduled for December 11. Other system maintenance remains scheduled for December 11 as follows.

CISL staff will update several key data analysis and visualization system components and the Campaign Storage file system beginning at 9:30 a.m. MST. The maintenance will affect the availability of the Casper, Geyser, and Caldera clusters and file transfers to Campaign Storage. The GLADE file system is expected to remain available throughout the day.

Maintenance on Casper, Geyser, and Caldera is expected to take until 12 noon MST. The work will include installing a new version of the SLURM resource scheduler. These clusters will not be accessible during the maintenance window. Also note:

  • All running jobs, interactive processes, and login sessions will be terminated when maintenance begins.

  • Jobs that are queued for execution or in a hold state will remain in those states until Casper, Geyser, and Caldera are returned to service.

Maintenance on the Campaign Storage file system is expected to take until 5 p.m. MST. Globus transfers will be suspended for the duration of the maintenance but will resume when the work is completed.
