Today I was getting this error when installing a new kernel on a server running Debian: /usr/sbin/grub-probe: error: Couldn’t find PV pv2. Check your device.map. The error can be reproduce by running the update-grub command. The day before, a new RAID disk was added to this server, so I suspected this could be the cause. [...]

Two years ago I wrote an article presenting some Linux performance improvements. These performance improvements are still valid, but it is time to talk about some new improvements available. As I am using Debian now, I will focus on that distribution, but you should be able to easily implement these things on other distributions too. [...]
Last week, I set up two dhcpd servers in a fail-over configuration. The goal is that when one DHCP server goes down, the other one takes over so that clients don’t lose their network connection. I read different tutorials on the web, such as this one of a fellow blogger and this documentation published by [...]
Since this afternoon, this server is now running Debian GNU/Linux Squeeze. Just like the previous system, this is a KVM virtual machine running on a HP Proliant DL185G5 host. The host server has always been running Debian. This was my last production system still running Mandriva. I might have forgotten to move over a few [...]
Quite some time ago I wrote a blog post explaining why I preferred Mandriva over other distributions. But I have now switched to Debian GNU/Linux, so it is time for an update. I will mostly compare with Mandriva because that is where I come from and what I know the best, although most points are [...]
Yesterday I migrated two servers at work to a new machine. The old machines were pretty underpowered: a Pentium III 1 Ghz system (with 384 MB RAM if I remember correctly) and a Pentium 4 system. The new machine is a Dell Poweredge R410 with a Xeon E5504 processor, 12 GB RAM and a PERC [...]
What I expected to happen some time ago, is finally becoming reality: Debian is now my favourite distribution for desktop systems. First I installed Debian on my new Samsung N210 netbook and I was very pleased with the result. Shortly after that, my father experienced a bug while trying to print in Firefox on Mandriva [...]
With the upcoming holidays in sight, I could not resist buying a netbook system to take along with me on my travel to Italy. So yesterday, I received a brand new Samsung N210. I chose this system because it is not too expensive and it appeared about the best netbook in this price class according [...]
Most people use a mix of QT/KDE and GTK+/GNOME applications on their Linux system. Because both QT and GTK+ use their own widgets (which are all GUI elements, like buttons, toolbars, menus, checkboxes, etc…) and theme engine, QT and GTK+ applications look different from each other. This is especially bad if you use KDE in [...]
Since two days, I have merged the main servers used by two research laboratories at work. One server was an old Linux server which really needed a hardware upgrade, and the other one was a Mac Pro machine running a flaky OS X Leopard. The new server is of course running Linux: Debian Lenny. It [...]
