Rolling reboots on owens and pitzer starting 18 Aug 2021
We will have rolling reboots of Owens and Pitzer cluster, including login and compute nodes, starting from 9am on August 18, 2021. The rolling reboot is for urgent security updates. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect about a 10 minute outage of login nodes during the reboot of login nodes. If there are interactive jobs started from a login node and that login node is rebooted, then the job will be killed.
