Linus Torvalds explains how the word should be pronounced.

Extending Logical Volume

I was only using a part of my external usb hard drive to keep backups and needed to extend the partition to accomodate the ever-growing backup files.

There are quite some ways to do this which can be referenced at and .

Below is a quick command line reference if you are familiar with the process already.

  1. I added an additional 10GB of space:
    # lvextend -L+10G /dev/vg00/lvol0
  2. Unmount the drive:
    # umount /mnt/usbdisk
  3. Check the logical volume:
    # e2fsck -f /dev/vg00/lvol0
  4. Increase the file system size to match.
    # resize2fs -pf /dev/vg00/lvol0
  5. Remount:
    # mount /mnt/usbdisk

Nagios and Oreon (Nagios web front end) installation and Configuration

Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.).


Lighttpd Webserver Installation and Configuration

Security, speed, compliance, and flexibility--all of these describe LightTPD which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, CGI, Auth, Output-Compression,URL-Rewriting and many more) LightTPD is the perfect solution for every server that is suffering load problems. And best of all it's Open Source licensed under the revised BSD license.
