Dear Expanse User, Starting Feb 24, 2025, two-factor authentication (2FA) will be required on Expanse. To avoid losing access, set up 2FA with Google Authenticator before this date. Instructions are in the Expanse user guide (https://www.sdsc.edu/systems/expanse/user_guide.html) in the system access section. For role accounts needing programmatic access, Science Gateway PIs will be contacted with further details. Other users with automation needs should contact SDSC user support via ticketing before Feb 24, 2025. SDSC User Services Staff

DUO has reported issues with phone-call-based authentication on their systems today, leading to some users being locked out for several hours for too many authentication failures. We do NOT recommend that ACCESS users employ phone-call-based authentication, as it is often unreliable, and prone to being abused. We strongly recommend that ACCESS users configure their DUO authentication to use the DUO App on a mobile device, and to use Push authentication. Other authentication methods, including Passkey or token-based authentication are known to work well. For more information about setting up DUO, please consult the documentation at https://guide.duo.com/universal-prompt#add-or-manage-devices.

Dear Expanse User, We will be working on the SDSC machine room power infrastructure from 9PM (PT), Feb 5, 2025 to 8AM (PT) Feb 6, 2025. This will impact power to racks 1-8, 16, and 17 of Expanse. We have placed a maintenance reservation on these racks for the duration of the work. This will impact job wait times as we get closer to the maintenance period but the remaining resources of the system will available through the maintenance and logins, filesystem access, and job submissions are not expected to be impacted.

The Gateway will remain accessible for existing users, in order to access any data on the system, but it will be impossible to run new jobs. We currently plan to fully turn off Gateway access for ACCESS accounts by March, 2025. Please feel free to reach out if you have any concerns via email at pace-support@oit.gatech.edu.

On Monday, January 6, 2025 at 9AM EST, Jetstream2 will begin a maintenance outage that will last through approximately 9AM EST on Thursday, January 9 (subject to change). This infrastructure maintenance is being done in conjunction with a third party vendor to update Jetstream2’s cooling system in order to accommodate a resource expansion. This maintenance outage will affect all primary Jetstream2 resources (CPU, GPU, Large Memory, and Storage) and user interfaces (Exosphere, CACAO). While existing instances at satellite regions will not be affected by the maintenance, the Exosphere and CACAO user interfaces will be inaccessible for all regions. When maintenance is complete, all instances will be returned to either a shelved or active state. If your instance was in an active, unshelved state, it will be brought back to that state. If it was shelved, it will remain shelved. NOTE: If your instance was in an errored, shutoff, or suspended state, it will be restored to an active state. We strongly advise all Jetstream2 users to review the states of their existing instances, as well as save and close their work prior to January 6. You can preserve your work by: - Safely shelving any active instances - Backing up essential data outside of Jetstream2 or creating images (https://docs.jetstream-cloud.org/general/instancemgt/#image) of your instances During the outage, please refer to the Jetstream2 status page (https://jetstream.status.io/) for the most up-to-date information. We appreciate your understanding and hope to mitigate any inconvenience this might cause. If you have any questions, please contact the Jetstream2 Support team at help@jetstream-cloud.org (mailto:help@jetstream-cloud.org?subject=).

Dear Expanse User, A maintenance is ongoing to update part of the datacenter power infrastructure. This has impacted more Expanse racks than we originally anticipated (due to cooling considerations) and as a result some of the jobs running on Expanse were impacted. The jobs will get a NODE_FAIL error in Slurm so they will not be charged SUs. We will update once the maintenance is complete and the nodes are returned to service. In the interim, Expanse will have fewer available nodes than normal so wait times will likely increase today. We are sorry for the unexpected impact and please send us a ticket (either ACCESS or SDSC ticketing system) if you have any questions. Thanks SDSC User Services Staff
