Devops Needs Sushi

To not yum or to not apt-get, that's NOT the question.

Over at the OPenARK blog Shlomi Noach argues that using apt-get or yum to install your MySQL instance will one day most likeley break your MySQL setup. Depdendencies, distros not shipping the MySQL version you want to use and on some distro’s indeed the mysql vs MySQL issue, agreed, it all makes things less trivial.

However why give up a clean packaged system if there are other ways out ?

First of all by claiming that such an installation can break a working production environment looks to me like admitting you don’t have a split development, production environment and that rather than testing stuff upfront indeed you just hack a long in production.

Irc vs Twitter err.. Identi.ca

Over 1.5 decade ago, a bunch of us were addicted to irc, I lived on channels such as #coders, #nlcoders, #demoscene, sneaked in on #vlaanderen to see when the Leuven locals were heading to the pub, then started joining multiple Linux and Open Source related channels around 94…

Then some weirdos had an alternative way of chatting ICQ, then the folks from Redmond reinvented the wheel… Luckily XMPP arrived and Jabber became the open alternative, but still all of this time irc stayed

Loadays CFP

I would like to point the crowd to the Call For Presentaions of Loadays. , the Linux Open Administration Days .

The Linux Open Administration days 2010 will be the first edition of a new conference focusing on Linux and Open Administration, we are trying to fill a gap for System Engineers and Administrators using Open Source technologies"

More details on the Linux Open Administration Days site

I’ll probably be there .. given the fact that the event will be 5 minutes from where I live .

Fosdem 2010

Fosdem 2010 was my 10th fosdem Edition (including the first OSDEM)
As every year Fosdem suffered even more from it’s own success.

On Friday evening ther was the obligatory Beer event… however as people need to eat to .. the Devops crowd fled the scene

I had made reservations for a 20 something group and with the CentOS crowd joining us (as there was some overlap anyhow) we were 25 when we arrived in the restaurant .

Upcoming Conference Talks

I know the biggest part of my fanclub already booked tickets for my upcoming presentations, but the other 2 might want to check their calendars to see if they aren’t missing out on the good stuff :)

Next Sunday I`ll giving a shortish overview of MySQL HA alternatives in the MySQL and Friends devroom at Fosdem.

March will bring me to Manchester again for the UKUUG Spring conference where I`ll be giving a longer version of that presentation with a strong focus on integrating with PaceMaker, and automating the whole boostrap procedure of a HA setup.

Implementing Raid Monitoring on a 3Ware 3w-9xxx based controller.

When you pull out a disk from your Raid setup it shows a warning in syslog

1. Jan 27 10:18:22 EL860 kernel: 3w-9xxx: scsi0: AEN: WARNING (0x04:0x0019): Drive
2. removed:port=1.
3. Jan 27 10:18:22 EL860 kernel: 3w-9xxx: scsi0: AEN: ERROR (0x04:0x0002): Degraded
4. unit:unit=0, port=1.

However if no one is looking at syslog that won’t really be helpfull.

3Ware provides a tool from their site called tw_cli which can be used to manage
the raid setup from the command line.

F12 Dependency failure

Fresh laptop arrived, obviously the first thing to do is to install the latest fedora. then do a full yum update.

However that failed with the following failed dependency\

1. mesa-libGL-7.7-2.fc12.i686 from updates has depsolving problems
2. --> Missing Dependency: libdrm >= 2.4.17-1 is needed by package mesa-libGL-7.7-2.fc12.i686 (updates)
3. Error: Missing Dependency: libdrm >= 2.4.17-1 is needed by package mesa-libGL-7.7-2.fc12.i686 (updates)
4. You could try using --skip-broken to work around the problem
5. You could try running: package-cleanup --problems
6. package-cleanup --dupes
7. rpm -Va --nofiles --nodigest

Now I don’t really use all the fancy compiz stuff so for now I can just solve it by running

Planet , Drupal Style

So when you setup an aggregator there’s this one thing you miss from a regular planet …the list of blogs with their individual Feeds.

I wanted to use this for planet.loadays.org again and realized I don’t know where I got this snippet from or if I wrote it myselve or whatever .. but I do realize that unless I document it here I won’t be able to point other people to it again :) So just create a block like this one :
