Expand A Partition That Is Part Of A Logical Volume Group While Server Is Running

I recently had a couple new CentOS Linux servers brought online at a colo that a company I work for uses. I had the colo do a very simple install of CentOS so I could handle the details without having to remove a bunch of packages we didn’t need. The servers have two one terabyte drives installed in a RAID 1 configuration which provides us with one terabyte of usable disk space and upon initial configuration had a logical volume group created with three logical volumes. Each of the logical volumes, which included /var, /usr, and /, only had two gigabytes of space so I needed to first expand those logical volumes and later will be creating a large logical volume used for database data. Below I describe expanding already existing logical volumes when there is room to grow in the logical volume group.

Reset Xbox 360 Display Settings From The Xbox 360 Controller

We have been refurbishing a bunch of Xbox 360’s lately in our computer shop and today I was going to test one out for an extended amount of time so I needed to find a monitor or something to display the output of the Xbox 360. I tried getting it working on a Dell 1950FP monitor which has a DVI input but it wasn’t working properly so I figured I would try to reset the display settings on the Xbox 360 to see if that would make a difference. Use the instructions below to reset the display settings on your Xbox 360 from the Xbox 360 controller.

Find Out Your ZenCart Version, Locate Zen Cart Version Info

I started some work on a online store today that is using Zen Cart open source e-commerce software to power the store. I love Zen Cart, which initially was branched off of osCommerce, to power online stores and have used Zen Cart or osCommerce to power online stores for going on a decade. The first thing you should always do when beginning work on an already established site is get all of the information about the software(Zen Cart, osCommerce, WordPress, etc.) that runs the web site and the software used to power the site(MySQL, PostgreSQL, Apache, Litespeed, etc.). Zen Cart makes the initial task of obtaining information about the site and some of the server software fairly easy. Use the information below to obtain the Zen Cart version.

How To Close A Window In Windows Without A Mouse

Similar to the situation I described in yesterdays article I was working on a computer with Windows XP Home Edition this past weekend and the mouse or touchpad was not working. I had navigated through various windows, control panels, etc. and needed to close some of them so I could continue. The problem was that I didn’t have a mouse and I was unable to tab to the red X in the top right corner to close the window. Use the information below to close windows on any Windows machine without a mouse installed.
