[Berzelius-users] Reminder: Maintenance downtime 2024-04-03 -- 2024-04-04

[Henrik Henriksson]

Dear Berzelius users,

This is a reminder about the planned maintenance downtime next week.

> We are currently planning for a maintenance window of two full working days,
> 2024-04-03 07:00 -- 2024-04-04 18:00. This particular window was selected based
> on the results of the downtime survey we conducted.
> 
> Inside of this window, the cluster will be completely unavailable. Please ensure
> you copy out any data you need before the downtime starts. We may return the
> cluster to operation earlier if possible, but don't count on this.
> 
> During the maintenance window, we will do the following:
> 
>    - Perform upgrades on our Lustre filesystem. This is the main reason for the
>      downtime, as we need to bring the filesystem completely offline for this
>      operation. We expect this to take two full days. From a user perspective,
>      little will change, but this is an important infrastructure upgrade.
> 
>    - Update Slurm to a newer version. We don't expect any user-facing changes.
>      The job queue should remain, unlike the previous maintenance window.
> 
> During the maintance window we may also try to fit in smaller tasks that require
> less risk to do while the cluster is out of production anyway, such as firmware
> updates. This will be minor changes that we don't expect to be user visible.

As always, please contact berzelius-support at nsc.liu.se with any questions or comments!

Kind regards,
Berzelius Staff
