It has been awhile since we have purchased workstation hardware for a new system. We settled on the Asus P4B w/ a Geforce2 MX400 AGP video card. As of February 2002, it seemed like the best CPU value was a P4 1.7GHz. We are running Sorcery GNU/Linux so we can squeeze out all of the […]
Linux Workstation w/ Geforce2 and Asus P4B
Running Linux on Sparc64
If you have some old Sun hardware you would like to run GNU/Linux on, the easiest way to get started is to use the CD-ROM images available at Aurora Linux. We’ve tried many different distributions, but the only one that we could get to load successfully is Aurora. Mebbe we are braindead, but if you […]
Using chkconfig & /sbin/service to manage run start up scripts in RedHat
Red Hat includes the checkconfig & service utilities to help you manage your start up scripts and save you a lot of typing. This is handy when you’re adding your own services and also in managing the already existing services. chkconfig is available if you want to use it on other distributions that may not […]
Gentoo Migration With Dump / ST15150
We have an old Sun box that won’t even run Solaris 8. Plus, Urbana wants to run Solaris 9 on the good Sun box, not GNU/Linux. After we optimized our system with Gentoo, we didn’t want to redo the compiles, especially on this slower box. We did a dump of the filesystem, installed Aurora on […]
Extending a Logical Volume
In this article, we set up Logical Volume Manager for GNU/Linux. We created a 12 GB device from 3 4 Gig drives, but only assigned 5 GB for our logical volume. Now, we are going to extend that volume. [Note: Before you do anything involving your partitions or volumes, make a complete backup. Make sure […]
Shrinking a Logical Volume With LVM
In this article, and in this article, we showed how to install and extend logical volumes with LVM. Now, we want to shrink the filesystem we created and the logical volume, so we can remove the drive. [Note: Before you do anything involving your partitions or volumes, make a complete backup. Make sure to set […]
Adding a RAID1 Device to a Volume With LVM
In this article, we freed up a disk from our volume so that we could reconfigure our system. In this article we will create and add a RAID1 device to our volume group. We removed /dev/sdg from our volume group, and /dev/sdh was unused, so let’s create a RAID1 device to add to our volume […]
Upgrading LVM To Version 2 and Patching The Linux Kernel
So far, we have been using a generic 2.4.24 Linux kernel with LVM enabled. We had to compile this ourselves because the stock Red Hat / Fedora kernels don’t support our hard disks. See this article for more details. [Note: Before you do anything involving your partitions or volumes, make a complete backup. Make sure […]
Setting System and Hardware Time On GNU/Linux
It is daylight savings time again. For those systems that don’t automatically sync their time, you may have to set this manually. If you are in the U.S, you can find the correct time here. Let’s set the system time: root@srv-1 u-1 # date Mon Apr 5 03:45:59 PDT 2004 root@srv-1 u-1 # date 040504142004 […]
Setting Up Logical Volume Manager
Logical Volume Manager (LVM) allows you to combine disks and create a single volume that can be mounted like a regular partition. It also allows you to add and remove storage. Make sure that you have the support for LVM compiled into your kernel. We set CONFIG_BLK_DEV_LVM=y on ours, and that worked well. [Note: Before […]
Finish Conversion And Expansion to Two RAID1 Devices With LVM
In this article, we recompiled our software and kernel so we could remove our /dev/sde drive. [Note: Before you do anything involving your partitions or volumes, make a complete backup. Make sure to set up a test system with the same kernel and distribution to see how this stuff works. This article was written using […]
Compiling the Linux Kernel for More than 1GB of RAM
Agatha recently purchased another stick of 512MB RAM. It turns out that by default you need to change the kernel for it to use more than 1GB of RAM. Actually, the cutoff is technically at 960MB. Here is the memory info with 1.5GB of RAM installed, but with high memory support disabled: usr-1@srv-1 proc $ […]
