Everything is a Freaking DNS problem

Devops Needs Sushi

DRBD2, OCFS2, Unexplained crashes

I was trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) .

Setting up a single primary disk and running bonnie++ on it worked Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ worked

When setting up ocfs2 on the /dev/drbd0 disk and mounting it on both nodes, basic functionality seemed in place but usually less than 5-10 minutes after I start bonnie++ as a test on one of the nodes , both nodes power cycle with no errors in the logfiles, just a crash.

PS. Craig from O’ReillyGMT gets the credit for inventing the new DNS acronym,

Weird Scenes inside the Tarball, Midnight Commander woes

I was transferring an apt repository to a remote site using the tarbal I created locally. When the first machines tried to do an apt-get update from that repository they failed to getthe package list.

Twitter Woes

This one has been sitting in the drafts for too long, but frankly there’s not much I have to add.
Twitter is acting weird , we all know that .. but the following movie really beats everything.

Yes that’s right what you are seeing is me logging into my twitter account, checking my @krisbuytaert
messages and seeing the @vti messages and then even taking full control of their (in the mean while deleted) account.

Really folks .. Everything is a fine dns problem :)

PS. Yeah yeah .. the real problem was a filesystem corrupted

Told Ya sooo

By now everybody and their neigbour has realized that indeed Everything is a funky dns problem, Frank is giving talks about it at ZooCamp, and Serge figured out the hard way the downtime of planet.geekdinner.be was due to a dns problem :)

But I told you different things before … and some of you listened others are still reinventing the wheel as we go …

Matt A. points out that the OpenBravo folks realized that one should try to build on top of Open Source projects rather than modify core code ..

ZooCamp

Last saturday was ZooCamp , also known as Barcamp Antwerp II

The location , the Antwerp Zoo, was the same as for the last CloudCamp Antwerp edition, so I was already pretty familiar with the location.

Lots of new people at ZooCamp and also a bunch of regulars..

My 4th barcamp and the 2nd where I didn’t do a presentation, I hope the fact that Inuits was sponsoring ZooCamp made up for that.. contributions can be done in different forms, and you can’t always keep coming up with new topics.

Fun with Google Docs Urls

I`m not a big user of docs.google.com , but occasionally I use it sharing a public document to work on with friends or collegues.

So we have this spreadsheet we’re sharing with some family and friends to swap Disney stickers. Google Docs has the option to publish that document publicly as html for others to view.

So I tried , and it generated me a very nice url

http://spreadsheets.google.com/pub?key=rtlvf2-JSU1Pw-oPtuIZBPg&output=ht…

My sleepy eye catched the A1:C300 ending part .. which was generated by the friendly popup that asked me if I wanted to show all Sheets, or just a range of the page.
