Case Study: Doing a Live Upgrade of Many Thousand Servers at Google from an Ancient Red Hat Distribution to Recent Debian-Based One - Marc Merlin, Google

Sign up or log in to save this event to your list and see who's attending!


This talk will look at how we upgraded our ancient linux distribution on all our production servers to a more modern one based on debian stripped down and built from source. We do live upgrades of running machines using an rsync-like rollout mechanism, and we switched distributions on the fly without rebooting (we built debs and converted them to rpms for install until the entire distribution was replaced and switched to dpkg). I'll explain the issue with package pre/post install scripts when you replicate on the file level and I'll give some design details of ProdNG, our production linux image, and how we built a hermetic self hosting distribution, including building a biarch 32bit distro on 64bit systems. I'll also explain how we review images before rolling them out.

Audience: sysadmins, engineers, and managers interested on how to deal with large linux image deployment and upgrade.
