Scheduled maintenance
We have scheduled maintenance two to four 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 complete
- The operating system of all nodes, including login and compute nodes, updated to RedHat 8.9.
- Home directories moved to our new storage system (project space has been on this storage system for several months).
- New default versions of several modules.
- A number of compiled programs have been affected by the update from RedHat 7.9 to 8.9. If you see a new error about a missing library, this may be the problem. Please contact us for a fix.
- R/4.4.0. Around the time of this maintenance, a vulnerability in versions of R earlier than 4.4.0 was reported. Most of the existing versions of R on Unity are affected by the missing library error (above). Until we have a clear path forward, we encourage use of 4.4.0. If that's a problem for you, please contact us. See also OSC's statement on the issue.

The new storage cluster has 4x10Gb uplinks to the Unity cluster and allows much faster data transfers. If you have a need for additional storage, please contact asctech@osu.edu.
