2026-01-30 Cheaha Head Node Migration
We will be moving the Cheaha head node from GPFS4 to GPFS5. Maintenance is scheduled from 5:00 PM January 30th, 2026 to 6:00 AM January 31st, 2026. During this time Cheaha will be unavailable. This move marks the final part of our storage infrastructure upgrade and data migration.
How will this impact your work?
- Cheaha will be unavailable, including via Open OnDemand (OOD at https://rc.uab.edu) and SSH.
- The Slurm scheduler, database, and supporting services will be offline.
- All jobs are submitted with a time limit. If the time from submission until maintenance is shorter than a job's time limit, that job will be held in queue until maintenance ends. This means jobs will not run during maintenance, ensuring jobs maintain a consistent state and do not need to be re-run.
