Reminder: HPC systems maintenance scheduled for Tuesday, October 29

October 24, 2019

CISL storage engineers will update GLADE’s operating system on Tuesday, October 29. The update is required to bring the file system up to current security and support levels. The maintenance will begin at 7 a.m. MDT and is expected to last until approximately 6 p.m. The GLADE system, Cheyenne and Casper clusters, HPSS tape library, data-access nodes, and the JupyterHub portal will be unavailable during the maintenance window although HPSS is expected to be returned to service by 11 a.m.

Active Globus transfers will be suspended as maintenance is performed; they will resume when GLADE is returned to service. System reservations on Cheyenne and Casper will prevent most batch jobs from executing after 7 a.m. that day. Batch jobs and login sessions that are still running at that time will be killed.
