When running ocfs2 on cLVM, openais+pacemaker setup, you may run into something like described below.

The symptoms:

umount /data1
mspx1d0:~ # tunefs.ocfs2 –fs-features=sparse,unwritten /dev/system/data1
tunefs.ocfs2: Unable to access cluster service while opening device “/dev/system/data1″
mspx1d0:~ # mount /dev/system/data1 /data1
mspx1d0:~ # tunefs.ocfs2 –fs-features=sparse,unwritten /dev/system/data1
tunefs.ocfs2: Configuration error discovered while opening device “/dev/system/data1″

Here is how to get past cluster check when running ocfs2-tools.

From hb_gui or crm stop mounting of the file system and ocf::ocfs2:o2cb resources.

Install ocfs2-tools-o2cb package

Do normal stack configuration using /etc/init.d/o2cb configure, but do not auto start on boot. Read the fine ocfs2 manual.

Bring ocfs2 online: /etc/init.d/o2cb online ocfs2

Start ocfs2 service: rcocfs2 start

Update cluster stack on your partition with ocfs2 filesystem: tunefs.ocfs2 –update-cluster-stack /dev/system/data1

Do your thing with ocfs2-tools, such as: tunefs.ocfs2 -v –fs-features=sparse,unwritten /dev/system/data1

Stop ocfs2 service and unload o2cb: rcocfs2 stop && /etc/init.d/o2cb offline ocfs2 && /etc/init.d/o2cb unload

Re-enable ocf::ocfs2:o2cb resources and run tunefs.ocfs2 –update-cluster-stack /dev/system/data1 again. Re-enable mounting from hb_gui.  Hope there is a simpler way somewhere that I am not aware of.

Baroda IT Association(BITA) presents the biggest IT exhibition in Gujarat, India on 24 – 26 January 2010 at the Akota Stadium, Baroda. We will be there with openSUSE Education Li-f-e DVDs, so come look us up. Bring USB stick (min 4GB) if you want Li-f-e on the stick.

Stellarium is a free software available for Windows, Linux/Unix and MacOSX. It renders 3D photo-realistic skies in real time.. With stellarium, you really see what you can see with your eyes, binoculars or a small telescope. Packages for openSUSE are available from Education repository on openSUSE Build Service via 1-click install.

India and many parts of Asia witnessed the longest annular solar eclipse of the millennium, next such event will take place after 1000 years. Stellarium helps to re-live the moments of this eclipse and explain what exactly was going on during the eclipse.

Select Southern most tip of India from the location menu (hit right side of the screen with mouse), set date and time : 11:30 am 15 January 2010. Search for “Sun”, sparebar to center it, zoom in with mousewheel. Give few clicks on the “Fast Forward” button.

The dialog boxes has strange rendering bug, for a workaround create /home/yourusername/.drirc with the following content:

<driconf>
<application name=”stellarium” executable=”stellarium”>
<option name=”texture_tiling” value=”false” />
</application>
</driconf>

Enjoy!

Last week was one of the biggest gathering of FOSS geeks from all over India and some from abroad at foss.in in Bangalore.  Unfortunately it was not as big as I had expected. Here are some of the pictures from the event, also managed to get some “FOSS celebrities” to pose with our DVD. It was fun meeting many people only known to me via IRC nick or Planet India. Over 250 Li-f-e DVDs were distributed, many students from various parts of India were also part of the event, students from DA-IICT and IIIT helped burn some DVDs too. Thanks Pradeepto and Srinivasa for KDE and GNOME t-shirts, it was great pleasure meeting again with openSUSE B’lore team, puthali, girishks, srinidhibs, ravim85, abharath and Ex-Novellite  Hardik Dalwadi(Cannonical).

openSUSE Education community is proud to announce openSUSE-Edu Li-f-e: Linux for Education based on openSUSE 11.2 . Li-f-e flavor bundles the best of softwares openSUSE has to offer, such as most popular Desktop Environments, educational application, development suites, multimedia, great user experience out of the box, and a lot more that is expected in a modern Operating System.

Some highlights of what makes this a very special distribution:

Just back from the combined openSUSE 11.2 and Ubuntu Launch party. We had over 120 people attending the event, much more than we had expected. Luckily we had enough of pizza slices and DVDs for all

The event started with the welcome by Prof. Vupul Kalamkar, PhD of Bachelors of Computer Application Department, Faculty of Science, the Maharaja Sayajirao University of Vadodara. The first presentation was by Kartik Mistry,  Debian Developer on how to get started with contributing to Free Software world.

Next up was my talk featuring all the goodies we have packed in openSUSE Edu Li-f-e based on the latest openSUSE 11.2. A very passionate discussion on “user friendliness” of GNU/Linux distributions vs M$ Windows erupted when asked from the audience what was preventing them from using Linux, hopefully we were able to convey the ease of use by demonstrating many softwares that are present on Li-f-e and live demonstration of coding java, and C# by Nitin. How much easy can it get then getting IDEs such as MonoDevelop, Netbeans, Eclipse and compilers of all major programming languages out of the box.Some videos were also shown, among them Shayon’s(he is the the dude behind the camera in all pictures) promo and the stylish arrival of the geeko ending the presentation with this great video.

The hybrid iso technology was really a WOW! factor, many participants didn’t know something like this was possible and were thrilled with seeing it in action.

There were few laptops getting Linux installed, some running Ubuntu and some openSUSE, tons of live USB sticks were created and every participant went home with Ubuntu and the Li-f-e DVD.

We ended the event with a lucky draw, 3 Ubuntu t-shirts, 2 openSUSE Li-f-e t-shirts, and 2 USB sticks with Li-f-e installed on them were the prizes. Kartik Mistry had a random number generator script picking numbers, unfortunately it kept calling people who had already left or repeating numbers, so we went old fashioned with everyone present writing their names on a piece of paper and esteemed faculties of MSU BCA doing the honors of drawing the name of the winners.

Some of the pictures from the event.

We surely had a lot of fun…

This appeared in todays The Times of India country’s number one English newspaper.
