[Nebula-users] Nebula downtime for updates Tuesday 2023-03-14, 15-17 CEST

[Kent Engström]

Dear Nebula users,

after discussion with MET's user representative, we have scheduled
downtime on Nebula for updates that require reboot of the servers.

The downtime will take place on:

Tuesday 2023-03-14, 15-17 CEST

As we need to reboot the login node, users will be logged out. This
will affect programs running there, and interactive node access.

During part of the downtime, new compute jobs will not start, but
apart from that, running or queued batch jobs should not be affected.

Nodes will also be upgraded but that will be done between jobs as usual.


Best Regards,
