Linux compute nodes and desktop machines will be rebooted on Thursday, June 8th for software and security updates. This includes both RHEL 6 and CentOS 7 systems. Updates will be applied to machines between 7:00 pm and midnight. In an effort to try and minimize any corrupted files or lost work, please save all your data and log out of any Linux systems before 7:00 pm.
The following is a list of machines that already have the updates, so you can test critical work beforehand:
We will also be bringing down several compute nodes early to begin the process of converting them from Red Hat 6 to CentOS 7. The following machines will be shut down at 10:00 am on Thursday:
The upgrade of crunchy6 will be delayed until the week of June 19th, to allow extra time for those who have not yet tested their code on CentOS 7.
If you have any processes running on these hosts, please migrate them to other servers before this time. We expect they will be back online by the end of the day on Thursday.
