OpenStack Summmit 2016 – Barcelona

OpenStack is much more than just a specific set of software with discrete features. OpenStack is also the community that comes together to collaboratively creates technology, innovate and puh the state of computing forward. OpenStack software powers digital bussiness at some of the biggest companies and scientific efforts in the world. Wal-Mart runs online retail on OpenStack. BBVA and Banco Santander run customer-facing workloads on OpenStack . The European Organization for Nuclear Reaseach (CERN) processes massive amounts of data from the Large Hadron Collider to analyzer the fundamentals of physics using OpenStack. And the OpenStack community shares lessons learned about cloud usage and the cultural shifts we face with the changing technology landscape of today.

25 – 28 October 2016

My first summit just passed.

Four days of adventures. I have never participated in a event so massive: workshops, talks, the Marketplace.

I felt comfortable speaking english, as I’m Spanish-speaker, language communication represented  one of my fears. Attending  to a international summit for first time, with  people from all over the world… I had to be able to share an interesting conversation. Finally, this issue was not big deal. I tried my best and I think people understand me  😛

I really enjoy being part of this event.



The four-days  summit is divided between the normal summit and the Design Summit, which is set on the last days. At Design Summits the developers community gathers to brainstorm the requirements for the next release, discuss the implementation details and connect with other community members.

I joined the Cinder room to be part of the discussion, and finally met the people behind the IRC. It was really intense and people discussed about the future of cinder and next releases.



I met  OpenStack interns for round 12 and some of the old rounds too. It was excited to share the activity and energy around OpenStack with them.

It was great to see such a diverse, global group of users, developers and business leaders at this Summits. I’m honored to be part of this community.



“How to become a significant contributor to OpenStack if you live outside the US”. Since I’m from Argentina: one of my main challenge are locale requirement. I really feel represented with this talk:

The power of community

Hello, what’s up?

I’m so happy to announce that  I talked about all I’ve learned in my internship with OpenStack in two events. My internship finished but not my contributions.

  1. ARGCONF  at RedHat Arg


I joined vkmc in her talk about The power of community. This was my first talk ever so I was an important experience for me.

I talked about the contribution workflow. Since this could be a bit confused for incoming people It’s cool to add this topic.  Workflow, and conventions are still an issue for me in such a bit community, but luckily it’s easy to find help.

Slides Argconf here

2. LinuxChixArg meetup

The most shocking of the meetup was that @stringarray an ex-outreachy intern attended!! She join us and talked about her experience working with Gnome 6 years ago.

We gave an especial place to Outreachy this time, talking about our experiences and time working on the internship. I hope attends enjoyed the meet as much as I did. We try to share of motivation with FOSS every day.


@cynpy shared our next events project: PyCon Argentina.


Something else?


I also join #OutreachyChat to advice applicants for the incoming round of Outreachy 😀


What’s next?

I’ll attend to OpenStack Summit Barcelona (24th-29th October)!! I can’t wait for it.

I ‘ll also attend to PyCon Ireland!


Working in my first RBD bug

The cinder manage command it’s only for independent rbd volumes. However, manage an already-managed volumes is allow by the api and there’re not exception raised.

When you try to manage an already-managed volume, you received an unhandled error: ‘UnboundLocalError: local variable ‘rbd_image’ referenced before assignment’

How to reproduce:
1)Create a volume:
‘cinder create 1 –name vol1’
2) try to manage the volume (you can check the host with ‘cinder show <vol1’s ID>’):
cinder manage <vol1’s host> <vol1’s ID>
3) On the c-vol you can appreciate the unhandled error.
When this happens the RBD driver should handle the error.

The RBD driver should catch the exception and show a custom message notifying the user.

So, trying to handle the problem inside the rbd driver.

Memory management

I realized if I have to write more about my work, I’ll have to throw around a lot of jargon and it’s not really fun if you haven’t yet had proper introduction to memory management terms or it’s been a while and you have trouble recollecting them. This post talks very briefly about some of […]

Thanks to my Outreachy’s partner :  The whatsit page — Tux-Mex

Let’s play with Cinder and RBD (part 1)

After you ./stack (you may have a cluster issue):

(1) You need to check out your ceph configuration and see if everything is ok.

~/devstack$sudo ceph -s
  cluster <uuid>
  health HEALTH_OK

To check the size of your cluster:

~/devstack$ceph df
