Scheduled maintenance on public gateways complete
This Saturday morning, April 20th, we will be taking the public gateway and portal servers offline from 7 am to 9 am in order to reboot and upgrade the operating system to CentOS 7.6 from 7.4 and the GPFS filesystem to 5.0.2 from 4.2.3.
Updating the entire cluster to GPFS 5 is an incremental but necessary step in the upgrade plan for /home. When paired with new solid state disk hardware, we expect that the filesystem will be much better equipped to handle the increasing demands of the growing cluster. In addition, the new version of GPFS may provide new tuning options that could improve interactive performance.
Please note that custom or private gateway servers will not be affected, and you may continue to log into these servers normally. We will in the near future need to schedule reboots for all custom gateway servers connected to the GPFS cluster.
