As I mentioned in my previous blog post, trying out Ganeti can be cumbersome and I went out and created a platform for testing it out using Vagrant. Now I have a PDF guide that you can use to walk through some of the basics steps of using Ganeti along with even testing a fail-over scenario.… Continue reading →
Ganeti is a very powerful tool but often times people have to look for spare hardware to try it out easily. I also wanted to have a way to easily test new features of Ganeti Web Manager (GWM) and Ganeti Instance Image without requiring additional hardware. While I do have the convenience of having access to hardware… Continue reading →
One of the best features of Ganeti is its ability to grow linearly by adding new servers easily. We recently purchased a new server to expand our ever growing production cluster and needed to rebalance cluster. Adding and expanding the cluster consisted of the following steps: Installing the base OS on the new node Adding… Continue reading →
Along with the rest of the OSU Open Source Lab crew (including students), I was invited to the grand opening of Facebook’s new datacenter yesterday in Prineville, Oregon. We were lucky enough to get a private tour by Facebook’s Senior Open Source Manager, David Recordon. I was very impressed with the facility on many levels.… Continue reading →
I’ve been asked quite a bit about how I do our network setup with Ganeti. I admit that it did take me a bit to figure out a sane way to do it in Gentoo. Unfortunately (at least in baselayout-1.x) bringing up VLANs with bridge interfaces in Gentoo is rather a pain. What I’m about… Continue reading →
I’m going to be speaking at SCALE 9x this year and giving a session on Scalable Virtualization with Ganeti on Saturday February 26th at 6pm. I will be going over the basics of what Ganeti is and how you use it. This session will be very similar to the ones I gave last year at Open Source… Continue reading →
Recently I had one of the nodes in a Ganeti cluster go down because of a faulty hard drive. Normally we would have RAID on machines in our ganeti clusters, but this particular machine didn’t. Having a machine go offline like that would usually be a big deal, but with ganeti and DRBD this isn’t… Continue reading →
After nearly a month and a half (42 days) of development since 0.4 was released, the OSUOSL has released Ganeti Web Manager 0.5 today. This second release has some very nice new features included in it: New status Dashboard Integrated noVNC, an HTML5 + WebSockets VNC viewer New Twisted based VNC Auth Proxy Virtual machine [...]
Want to work at the coolest place for open source and support the missions of some of the most important open source projects? Oregon State University’s Open Source Lab is recruiting a full-time software developer who will analyze, design, and test software code for Ganeti Web Manager, the Protein Geometry Database and several other homegrown [...]
Lead OSUOSL Developer Peter Krenesky has written an excellent blog post going over how the permission system works in Ganeti Web Manager. A key feature I’m looking forward to using more at the OSUOSL is managing our clusters with the following scenarios: Fully managed – users have no access at all. Only admins can create, [...]
