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 am a total linux Noob but my server keeps crashing, looks like hard drive error, but I dont have any SMART errors, and the array seems ok.
Looking for some help, this keeps on happening to my RHEL4 64bit Hugemem machine running vmware and it takes down the server.
I am running a Supermicro box with Dual Quad Core processors and 16GB of mem,
There are two arrays One Mirror set for the system and a RAID 10 for the VM volume.
The machine halted, no console, no ssh, only responds to ping, I see this in all the virtual terminals
ext3-fs error (device dm-0) in start_transaction:Journal has aborted
and after several hours of several days it happens again.
here is a section of /var/log/messages
it is interesting to note All the had and Ide errors and how at 12:32:12 last night the log just stops and then it picks up again at 22:39 when I rebooted it. Also after the reboot, the exact same errors start occurring again.
Well, from looking at the logs, yes, it appears to be a hard-drive error however, you stated that hda is part of a raid container. I'm assuming hda is raid 1. Therefore, if there was a hard-drive error, no big deal as it's part of a mirror anyways. Perhaps the controller is faulty/dying. Does the server come with any diagnostic tools (or on a CD like how dell has it) that you can run and perform a system component health check?
It would probably also help if you had another identical system and install RHEL on it and see if it mimics the same behavior. However, I understand if you don't.
