Ubuntu Weekly Newsletter – Spanish Translation Efforts

The Ubuntu Weekly Newsletter is translated in many languages every week, but what I’ve noticed is that the Spanish translations have been abandoned. The last translated issue is Issue #95 (you can see it here: [1]).

I believe that there’s many people that would like to read it in their own language rather than English, and that would like to read more about local news. This is way I’m retaking the efforts to translating it into Spanish. The latest Issue (Issue #121) has been published here: [2] (It is not finished yet and needs review).

One thing that is important to know about the UWN translations is that we don’t have to translate it literally. We can include local news, such as news about Spanish speaking LoCo Teams, or more Ubuntu Related News in Latin America/Spain. So, if you want to collaborate in the translations efforts, in making it a better UWN in Spanish, or reviewing it, just contact me:

  • RoAkSoAx on #ubuntu-pe, #ubuntu-es, (and many other channels).
  • andreserl AT ubuntu-pe DOT org

UPDATE: Ubuntu Presentation!

On November the 21st and November the 22nd, there will be the “I Free Software Conference and Installation Festival” at National University of San Agustin, Arequipa – Peru. It is a great pleasure for me to announce that the Ubuntu Peruvian LoCo Team is going to participate giving a presentation of “Ubuntu Intrepid Ibex”. Btw, I’m the one who’s giving it =). I’m also going to talk about “HA-Clusters in Ubuntu”, which is a topic related to my thesis.

Well, anyways, It is also great to announce that Richard Stallman will be participating on the 22nd, giving a conference about “Human Rights for Software Users”. This event will gather almost 250 people. So, if someone from Arequipa – Perú gets to read this post, I hope to see you there!

Btw, The National University of San Agustin is migrating to Ubuntu… So, it is following UNMSN example. Well, wish me luck because after tomorrow, many people will be turning to Ubuntu :).

UPDATE: I’m updating this post to let people know that the event is finished and many people are turning to Ubuntu, and got interested on how to contribute, specially in Development and the LoCo. Hopefully, they will start their participation pretty soon. However, the most impressive thing that happened, is that a TV Show interviewed me after the conference and wanted me to explain them more about Ubuntu, what are the benefits of using it, if it’s pretty well known among organizations, and things like that. Well, I just have a couple of pics since my camera died. Enjoy =).

DRBD and NFS

Hey all. Sorry for the delay in posting this tutorial, I’ve been pretty busy and I finally had some time to finish it. Enjoy :).

Well, as you may know, in previous posts (Post 1, Post 2) I’ve showed you how to install and configure DRBD in an active/passive configuration with failover, automatically, using Heartbeat. Now, I’m going to show you how to use that configuration to export the data stored in the DRBD device (make it available for other servers in a network) using NFS.

So, the first thing to do is to install NFS in both drbd1 and drbd2, stop the daemon, and remove it from the upstart process (This means that we’ll have to remove the NFS daemon from starting during the boot up process). We do this as follows in both servers:

:~$ sudo apt-get install nfs-kernel-server nfs-common
:~$ sudo /etc/init.d/nfs-kernel-server stop
:~$ sudo update-rc.d -f nfs-kernel-server remove
:~$ sudo update-rc.d -f nfs-common remove

Now, you may wonder how is NFS going to work. The NFS daemon will be working only in the active (or primary) server, and this is going to be controlled by Heartbeat. But, since NFS stores information in /var/lib/nfs, on each server, we have to make both servers have the same information. This is because if drbd1 goes down, drbd2 will take over, but its information in /var/lib/nfs will be different from drbd1‘s info, and this will stop NFS from working. So, to make both servers have the same information in /var/lib/nfs, we are going to copy this information to the DRBD device and create a symbolic link, so that the information gets stored in the DRBD device and not in the actual disk. This way, both servers will have the same information. To do this, we do as follows in the primary server (drbd1):

mv /var/lib/nfs/ /data/
ln -s /data/nfs/ /var/lib/nfs
mkdir /data/export

After that, since we already copied the NFS lib files to the DRBD device in the primary server (drbd1), we have to remove them from the secondary server (drbd2) and create the link.

rm -rf /var/lib/nfs/
ln -s /data/nfs/ /var/lib/nfs

Now, since Heartbeat is going to control the NFS daemon, we have to tell Heartbeat to start the nfs-kernel-server daemon whenever it takes the control of the server. We do this in /etc/ha.d/haresources and we add nfs-kernel-server at the end. The file should look like this:

drbd1 IPaddr::172.16.0.135/24/eth0 drbddisk::testing Filesystem::/dev/drbd0::/data::ext3 nfs-kernel-server

Now that we’ve configured everything, we have to power off both servers, first the secondary and then the primary. Then we start the primary server, and during the boot up process we’ll see a message that will require us to type “yes” (This is the same message showed during the installation of DRBD in my first post).  After confirming, and If you have stonith configured, it is probable that drbd1 wont start its DRBD device, so it will remain as secondary, and won’t be able to mount it. This is because we will have to tell stonith to take over the service (To see if stonith is the problem, we can take a look at /var/log/ha-log). So, to do this, we do as follows in the primary server (drbd1):

meatclient -c drbd2

After doing this, we have to confirm. After the confirmation, Heartbeat will take the control, change the DRBD device to primary, and start NFS. Then, we can boot up the secondary server (drbd2). Enojy :-).

Note: I made the choice of powering off both servers. You could just restart them, one at a time, and see what happens :).

CISAISI 2008

CISAISI 2008 (Congreso Internacional Sud-Americano de Ingeniría de Sistemas, Computación e Informática 2008), is an International Latin American event of Systems Engineers, Computing and Informatics. This event is on its XII edition and it will be in Arequipa – Perú, from the 6 to the 10th of October, at Universidad Católica de Santa María – UCSM, which is the University where I’ve studied.

This event was created to do courses and debates, give conferences and summit scientific work. On the present edition of the CISAISI 2008, a new feature has been added, which is the “Poster Contest”, that allows young people, such as students, to summit any scientific work they are working on, related to Informatics.

On this edition, I summited my Thesis as a paper for this “Poster Contest”. This means that I’ll be presenting my Thesis (“Designing a Model to Implement High Availability Web Servers”), and talk about it during the event. This event is very important because many people from different cities around Latin America are going to be present. This is a good chance to promote Ubuntu in Cluster utilization, since my Thesis was done creating clusters in Ubuntu. This will show to many people that Linux, and specially Ubuntu, is a powerful OS to create High Availability Clusters. This will also introduce DRBD to the Latin American Market.

So, whish me luck!! :).

Brainstorm Idea Support

As you may know, I applied for JJ UDS Sponsorship. I think that today was the last that people could summit their ideas. But, people can still support them I guess. Since I have been pretty busy the past few days, I just got some time to explain my ideas a little more.

My first idea is Centralized Cluster Administration. This idea is related to the creation of an application that will help us implement and manage LVS Based Clusters. I got this idea because, as you may know, I did my thesis about Designing a Model to Implement High Availability Web Servers using LVS based clusters.


My second idea is Ubuntu Centralized Image Installation/Recovery/Backup. This idea is related to the creation of an application that will help us install Ubuntu from a centralized server on a LAN, similar to what RIS is. It will also allow us to create images, and be able to recover them and create backups, and so on.

So, if you think they are good ideas, it would be great to have your support. Thanks :).
