Unscheduled service break on Mahti: May 4 8:00 to May 5 12:00

Mahti has an unscheduled maintenance break  from Tuesday May 4 at 8:00 to Wednesday, May 5 at 12:00. During this break compute nodes, login nodes and storage will be unavailable.


During this service break the storage system operating system and software stack will be upgraded.  It is important to do this as quickly as possible to ensure the stability and health of the storage system. The long duration fo the break is an unfortunate consequence of the complexity of the upgrade process.


Jobs that can finish before the break will execute normally, and any jobs that are queuing when the service break starts will be able to run after it has finished.
