Date of downtime: Tuesday, September 27, 2022
Approximate time of outage: 7am-5pm
Resources affected by downtime:
UB-HPC cluster (all partitions)
Faculty cluster (all partitions)
Portals: WebMO, OnDemand, ColdFront
What will be done:
Reboot of all cluster nodes
Updates of front-end login nodes (vortex1/2)
OnDemand updates
Infrastructure updates (FreeIPA, DNS)
ColdFront update
Noticeable changes for OnDemand users: Desktop and Jupyter apps no longer allow requesting more than 1 node. Anyone requesting more than 1 node wasn't actually utilizing the additional nodes as they were not accessible from with the "head" node. If you require more than one node, please use a Slurm batch script or contact CCR Help for assistance with your application.
Jobs will be held in queue during the maintenance downtime and will run after the updates are complete.
If you have any questions or concerns please e-mail ccr-help_at_buffalo.edu
