Maintenance: HLRN system Emmy from 2022-09-20 08:00 CEST to 2022-09-21 21:00 CEST

The HLRN system Emmy in Goettingen will have a downtime from September
20th 8am until Thursday September 22nd.

This downtime is needed for updating the Lustre WORK storage. These
updates include the final patch for the Lustre metadata bug, we have
experienced from May until July and we have received a preliminary
patch. Additionally this updates includes updates for a few smaller bugs.

Additionally we will use this downtime to install necessary software
patches on all core servers and compute nodes as well as preparing the
network infrastructure for the installation of our upcoming GPU
partition with AMD Epyc nodes with 4 Nvidia A100 GPUs at the new GWDG
main data center RZGÖ.

We apologize for the inconvenience.
