Scheduled maintenance
We have regularly scheduled maintenance two or three times a year.
Two weeks before scheduled maintenance, the Slurm scheduler will begin holding submitted jobs that could run past the beginning of the maintenance window (shorter jobs will run normally). If you see a status like (ReqNodeNotAvail, Reserved for maintenance) for a job in the output of the squeue command, that's what's going on.
May 6, 2024 maintenance
Unity will be unavailable on May 6 for scheduled maintenance. Updates will include:
- The operating system of all nodes, including login and compute nodes, will be updated to RedHat 8.9 (from 7.9). The 24 newest nodes (in the batch8 partition and various user partitions) have been running 8.9 for a couple months.
- Home directories will be moved to our new storage system. Project space has been on this storage system for several months.
- New default versions of several modules.
Please direct any questions to asctech@osu.edu about the downtime and notify us about any issues occurring after this window.
