Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I/O error typically means your cpu and hdd are no longer able to communicate with each other. Have you tried rebooting? That will tell a lot. If reboot fails, open the box and make sure all cables are still connected. If that's not the problem, you've most likely suffered a hdd crash. But sometimes rebooting solves the problem. Computers still suffer glitches.

THANKS for your response! This is totally ruining my Sunday. I have called the hosting provider and no one has gotten back to me. I think you are right. The system has 3 hard drives in it, however: backup, database, and system/php/apache/etc. I'm totally on pins and needles waiting on tech support.
You can also get screwy results if the drive that your logs are on gets full. It does not take long to fill up a drive if something goes a little wacko and you get a repeating log every few seconds. Ext3 normally reserves overhead just for this purpose but some vendors remove this to gain more space.
The system has 3 hard drives in it, however: backup, database, and system/php/apache/etc.
It then fails to respond to any commands at all.
From these two quotes, it seems your system/php/apache/etc drive is not communicating. Have you tried rebooting, yet? If it does reboot correctly, check the free space on each drive per lazlow's suggestion.
Start by deleting unnecessary log files. If something went awry to cause a runaway log to fill the drive, find and correct the error to prevent it from reoccurring. If everything is working properly, replace the drive with a larger one, or piggy-back another drive to the system.
