News and Announcements from the MCS Systems Group

Upgrading v8.mcs.anl.gov 7/11/16

We’ve got a two phased linux compute environment upgrade we’re in the process of doing this year. Phase one is rolling out an Ubuntu 14.04 build (aka Trusty), and phase two will be rolling out a CentOS 7 build. Phase two won’t be starting until end of summer, but phase one is already under way, with some destops and servers serving as early tests.

The server v8.mcs.anl.gov is running a very old Ubuntu Build (10.04, aka Lucid), so we’re going to target that as the first of the compute servers to get the upgrade.

We’ll be taking the machine down on Monday morning, and reinstalling it as Trusty, at which point we’ll announce when it’s back up and encourage you to use it and let us know what’s missing from it. This will allow us to fine tune the Trusty environment and make sure all the machines running at that level are best suited to your needs.

What you need to do: If you’ve got data in the /sandbox on v8, make sure you’ve got it copied elsewhere, since that will be erased. If you’ve got cron jobs that run on v8, make a copy of your crontabs so you can replicate them on the new v8.

After we’re done getting that machine in a good state for your needs, we’ll announce the schedule of the updates to the rest of the compute servers. At that time we’ll also ask for more volunteers to have their desktops updated.

If this outage poses a significant problem for you, please let us know so we can reschedule it.
