RedHat Cluster, and some more
Byetzion 12/02/2006

It’s been a long while since I’ve written. I get to have, once a while, a period of time dedicated for laziness. I’ve had just one of these for the last few weeks, in which I’ve been almost completely idle. Usually, waking up from such idle time is a time dedicated to self studies and…

Byetzion 16/05/2011

Recently, bonding module requires IPv6 module. There are two possible solutions. The first is to define zeroconf to off, by adding the following line to /etc/sysconfig/network : NOZEROCONF=yes The other method, which actually disables IPv6 is to insert into /etc/modprobe.conf the following line: options ipv6 disable=1 That should do the trick.

Adding modules to Damn Small Linux (DSL)
Byetzion 30/01/2009

This is not a simple task. Adding or compiling modules is a tricky feat when it comes to 2.4 kernels. It requires you compile the entire kernel yourself before. I have used a diskless machine, with an NFS mount as the place where I have kept all persistent data. Mounted it at /tmp/mnt directory. Preparations…

Gain Control of the Storage Controller Loading Order
Byetzion 20/07/202325/07/2023

I encountered an intriguing issue recently after replacing my motherboard. Some block devices underwent a change in their order, causing /dev/sda to appear as /dev/sdy due to a modification in the PCI-e enumeration. This change, though seemingly insignificant, led to an unexpected consequence. Since the disk was subject to a specific mdadm filter, its altered…

Radeon 9600 Dual Display (dual-head)
Byetzion 21/06/2006

After much agony with my faulted NVidia Dual-head card, and the frequent hard-freeze which were part of this experience. A new and shining ATI Radeon 9600 has entered my AGP slot, and I was ready to make it rock. First thing first – I utterly failed to install the damn driver. ATI build their drivers…
