We need to apply an emergency security update to our gitlab servers.  Affected servers are git.cels.anl.gov, gitlab.cels.anl.gov, xgitlab.cels.anl.gov.  Sorry for the short notice, but that’s how security updates sometimes come our way.

As one can surmise by the title, as well as for anyone who cares to check the history of these things, my aspirations of a monthly newsletter have evolved into “Every other month isn’t too bad, right?”  Polite readers will refrain from pointing out it’s already May.

The majority of the GCE compute nodes have been rebuilt and are back online at this time. We have also added a few nodes with this work. Please see virtualhelpdesk.cels.anl.gov/docs/linux/login-compute-and-home-nodes/ for an updated list of current hostnames/configurations as some nodes have been renumbered. As most of the nodes are now running ubuntu 20.04, if you …

On Monday, Feb 14, 9:30am CST, we will be taking down the following GCE compute nodes: compute-03.cels.anl.gov, compute-04.cels.anl.gov, compute-05.cels.anl.gov and compute-06.cels.anl.gov for system upgrades. This upgrade will require about 4 hours of downtime. When they come back up, they will be running the most recent GCE compute/workstation build (Ubuntu 20.04). This will not affect data …
