GlusterFS CLI code follows client-server architecture, we should keep that mind while trying understand the CLI framework i.e. “glusterd” acts as the server and gluster binary (i.e. /usr/sbin/gluster) acts as the client. In this write up I have taken “gluster … Continue reading →
Introduction I recently tried to set up OpenStack with docker as the hypervisor on a single node and I ran into mountains of trouble. I tried with DevStack and entirely failed using both the master branch and stable/havana. After much work I was able to launch container but the network was not right. Ultimately I […]
New Linux Container Virtualization Technology from Docker
The Docker, new container-based virtualization tech startup has started it’s venture to the server virtualization industry by offering their newest version of the software, the Docker 0.8. The company has been known for their production of a faster alternative when it comes to running virtual machines over that of hypervisors.
In this post I’ll try to keep a running tally of distinctions between distributed and non distributed algorithm implementations in mahout, as it can be tricky to keep track of sometimes. When using mahout its important to know what implementation…
This is an example of how to configure an environment where you can test CloudStack and Gluster. It uses two machines on the same LAN, one acts as a KVM hypervisor and the other as storage and management server. Because the (virtual) networking in the …

Background: I had an existing Windows Server 2008 R2 machine running 12 VMs utilizing local storage, but quickly outgrew the specs of that machine. This meant a migration to new hardware as well as an upgrade to Windows Server 2012…
I’ll be giving a talk at SCALE today about automatically deploying GlusterFS with Puppet-Gluster and Vagrant. I’ll be giving some live demos, and this will cover some of the material from: Automatically deploying GlusterFS with Puppet-Gluster + Vagrant! and it … Continue reading →
Vagrant lets you reproduce a pure linux box, anywhere, automatically, but it comes at the cost of provisioning a brand new VM, which takes a while. Docker, on the other hand, gives you a lightweight framework for running containerized, layered so…
As a part of GlusterFS 3.5 testing and hackathon, I decided to put GlusterFS inside a docker container.So I installed docker on my Fedora20 desktop and then started a Fedora container Once I am inside the container I installed GlusterFS … Continue reading →
The bigtop smoke tests are a great way to hit your cluster with a broad range of hadoop workloads.One of the things I learned from running the diverse workloads that they offer for hadoop on top of gluster, is that gluster is really modular. Some…

After four days of FOSDEM and CfgMgmtCamp, you might suspect that people would be too tuckered out to turn up for one more day of conference – but you’d be wrong. More than 80 people, almost all who’d been at FOSDEM and CfgMgmtCamp, turned up last Wednesday in Ghent for the first Infrastructure.Next.
The idea for Infrastructure.Next is to focus on “the future of the datacenter,” whether that be specific technologies, best practices, or culture that will enable teams to adapt and evolve as needed.
What’s the optimal length for a talk? These days, more and more events are settling on 30-minute talks for high-level concept talks. An hour is, truly, a daunting amount of time to fill – and with some preparation and practice, most speakers can distill their ideas and content into a 30-minute talk that will be more likely to retain the audience’s attention. So, with one or two exceptions, we set the time limit to 30 minutes for the speakers, with good results.
What a group of speakers we had, too! The day kicked off with CentOS contributor Jim Perrin, who walked through the recent changes in the CentOS community and a preview of what people could expect from CentOS in the near future. (Not to mention, how they can get involved directly to help influence CentOS and be part of the community.)
David Nalley of Citrix and a PMC member for Apache CloudStack gave an excellent talk on the operational requirements for cloud. This was an interesting contrast to Brian Proffitt’s talk immediately after, which asked whether cloud was really necessary for every organization. Had we a bit more time, it would have been interesting to put Proffitt, Nalley, and a few other speakers on a panel for their views on where data centers are (or should be) going this year.
Data centers do not live by IaaS alone, though. Diane Mueller finished the morning talks with a discussion about PaaS, specifically OpenShift, and the benefits it confers for organizations.
Michael Ducy of Chef was on hand to reprise his talk from the London Cloud Summit, “The Road to Hybrid Cloud is Paved with Automation.” As in London, Ducy’s talk inspired quite a bit of conversation – though it was a bit more difficult to engage the audience in the much larger room.
We also had a few good down-and-dirty technical talks on using specific technologies, courtesy of Doron Fediuck and Rich Bowen. Fediuck explained how to extend oVirt to fit your needs, with a couple of fun examples. Bowen discussed the importance of measurement and explained how to use OpenStack Ceilometer, which also kicked off some interesting discussions on monitoring and the right way to use such tools.
John Mark Walker and Sam Kottler had interesting talks that looked at emerging technologies. Walker, community leader for Gluster, discussed the future of data management, while Kottler looked at the changes in application deployment and how containerization is going to influence app deployment.
Leslie Hawthorn, community manager for Elasticsearch, discussed how organizations could apply DevOps principles for “happier, more productive people.” Not in terms of “if you’re practicing DevOps, you’ll have happier people,” but actually using the principles around working with people in your organization. It was an approach I hadn’t previously considered, but it certainly made sense.
The closing talk for Infrastructure.Next came from Fedora Project Leader Robyn Bergeron, “You won’t believe the amazing things you ALREADY KNOW about DevOps from working in an open source community!” The tongue-in-cheek Upworthy-styled title aside, it was a really solid discussion and a great close for a long day of talks.
The event was sponsored by Red Hat, but would also not have been possible without the cooperation of our hosts from the University College Gent and the CfgMgmtCamp organizers. The facilities were top-notch, and everything went off without a hitch thanks to their assistance.
Contrasted with the London Cloud Summit the audience was a tad more subdued. No doubt, part of this was due to event fatigue. After three or four days of conferences, the spirit may be willing, but the flesh is just barely getting by on coffee and sheer willpower.
But, more than that, a larger crowd and larger room plays against the feeling of intimacy required to have a really good interaction. As we plan more events for 2014, we need to find a sweet spot between reaching the most people and ensuring that those in attendance are deeply engaged and getting the most out of the event.
If you missed Infrastructure.Next in Ghent, or just didn’t get enough the first time out, you can sign up for Infrastructure.Next @ SCALE. Co-located with SCALE 12x, tickets are free but registration is required. Sign up today!
We’re also looking to co-locate Infrastructure.Next with other events. If you have an event we should consider, please get in touch!

In the open source software world, every day can be a test day, but there’s plenty to be gained when community members converge on an IRC channel to nick themselves on a project’s cutting edge. This month, there’s a handful of test days on tap:
Following the OpenStack Icehouse milestone 2 release, the RDO project is holding a pair of test days on February 4th and 5th. For more information, and to indicate that you’ll be participating, head to the test day page on the RDO wiki.
The beta3 packages for Gluster 3.5 are expected to hit FTP this week, with a GlusterFest testing weekend to follow. This one is still somewhat TBD, so check the Gluster project site and mailing lists for updates and confirmation.
oVirt 3.4 is nigh, with a projected general availability date of February 24th.
Leading up to the final 3.4 release, there’s a pair of test days scheduled for shaking out as many issues as possible ahead of the release. For more information, see the 3.4 test days page on the oVirt project wiki.
The Fedora Project isn’t holding any test days for February, due in part to a longer-than-normal lead-in period for Fedora.next, an umbrella term for the “shape of Fedora in the post-F20 future.”
However, Fedora QA titan Adam Williamson offered up a great list of suggested testing activities during the pre-F21 lull that’s well worth reading and acting on.
And, speaking of Fedora.next and Adam Williamson, Adam wrote a very insightful post about the new initiative and Fedora’s near future, based on the recent discussions of these matters in the Fedora community.
I decided to record some screencasts to show how easy it is to deploy GlusterFS using Puppet-Gluster+Vagrant. You can follow along even if you don’t know anything about Puppet or Vagrant. The hardest part of this process was producing the … Continue reading →
