Sun May 22th, 2022, 2:54 am: Automatic shutdown down due to power/Cooling.
Fri May 6th, 2022, 11:35 am: HPSS scheduler upgrade also finished.
Thu May 5th, 2022, 7:45 pm: Upgrade of the scheduler has finished, with the exception of HPSS.
Thu May 5th, 2022, 7:00 am - 3:00 pm EDT (approx): Starting from 7:00 am EDT, an upgrade of the scheduler of the Niagara, Mist, and Rouge clusters will be applied. This requires the scheduler to be down for about 5-6 hours, and all compute and login nodes to be rebooted. Jobs cannot be submitted during this maintenance, but jobs submitted beforehand will remain in the queue. For most of the time, the login nodes of the clusters will be available so that users may access their files on the home, scratch, and project file systems.
Monday May 2nd, 2022, 9:30 - 11:00 am EDT: the Niagara login nodes, the jupyter hub, and nia-datamover2 will get rebooted for updates. In the process, any login sessions will get disconnected, and servers on the jupyterhub will stop. Jobs in the Niagara queue will not be affected.
Tue Apr 26, 11:20 AM EDT: A Rolling update of the Mist cluster is taking a bit longer than expected, affecting logins to Mist.
