This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.
When existing computing facilities were not meeting the growing need of students and teachers at the Lorien Novalis school in Dural, NSW, students suggested that the school investigate open source software as a cost effective way of improving its computing power.
I know I’m not the only person who doesn’t like to feel like a beginner whenever I use a computer. There are those of us who only like to use something that they can easily master within a few minutes. Fear of feeling like a beginner is a major reason why people have avoided Linux. I’m definitely part of the target audience for the Linux LiveCDs.
Now, I’m not one of those naive, faintly embarrassing Linux evangelists, who is going to claim that Linux can cure piles, acne, hiccups or halitosis. But it strikes me that it does have a role to play in reducing the mountain of waste or, at least, postponing the evil day when another obsolete PC is tossed on the proverbial scrapheap.
It's a known fact that although disk storage capacities are improving at an impressive rate, disk performance improvements are occurring at a rather slower rate. Here are the two techniques for measuring disk performance in Linux. With a little bit of torturing, and some fun on the way, find out how fast your hard disk drive really is.
Dreamlinux is an operating system that boots from a Live-CD with the option to install on a hard drive as well. Dreamlinux is not just another Live-CD based on Debian, it’s not another distro coming with XFCE 4.4. Dreamlinux 2.2 MME is a polished multimedia system from which Xubuntu developers could really learn a lot.
Learn how to configure a p5 server to provide redundancy and recoverability in a production environment. You should already be familiar with how to create and configure a VIO Server and an LPAR.
Figuring out the best Linux distribution depends entirely on one's intended use for the program. As open source, freely distributed software, Linux programs have been modified and redesigned in countless ways to fulfill as many needs. However, some versions have proven more popular than others.
Perhaps one of the best Linux distributions tailored for older hardware is DeLi Linux. It's simple, and performs well enough to run on hardware as old as a 486. In fact, DeLi Linux runs on anything better than a 386 with at least 4MB of memory, though if you have only 4MB, don't expect stellar performance.
Giving desktop Linux a larger market share? To be honest, this can be a touchy subject for me, personally. Much of the reasoning behind my "rough feelings" on the matter stem from the fact that I disagree with much of the Linux and Microsoft camps in general. That's right, I think that large numbers from both groups are wrong, and it's because of this that each OS is experiencing so much trouble now in the press.
