The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

CentOS 4 Software RAID 1 Configuration

Asked by Maxwellb in Linux Setup

Tags: centos, raid, software, 1, configuration

Hello,

I have attempted to install CentOS 4 using software RAID but utterly failed. The Goal is to have a set of SATA hard drives completely redundant so that if one fails, nothing has to be done for the second to continue operating. I was also experiancing this error durring the install:

"There was an error installing *RANDOM PACKAGE NAME*. This can
indicate media failure, lack of disk space, and/or hardware problems.
This is fatal error and your install will be aborted. Please verify your
media and try your install again."
(http://www.experts-exchange.com/Operating_Systems/Linux/Linux_Setup/Q_21395656.html?query=This+can+indicate+a+media+failure%2C+lack+of+disk+space&clearTAFilter=true)

But I believe I have determined that the cause of this is not enough RAM for the complex installation (192mb, 64 reserved for video that I can't disable?...)

Anyways, the issue is that after I reboot after completing a seeminly successful install I recieve GRUB errors (usually, "GRUB GRUB GRUB") or another that I cannot recall. My objectives are basically covered in:
http://www.experts-exchange.com/Operating_Systems/Linux/Linux_Administration/Q_21647293.html?query=CentOS+Software+RAID&clearTAFilter=true

However, as I am a complete "newbie" to linux was wondering if there is any other way than the complicated procedures listed in the above solution. As well, I wanted to create a "logical" volume so a text install will not work (Correct?).

This is the partitioning I wish to have in exact replication on both drives (Software RAID 1): (The drives are 160GB SATA)

100mb: /boot
1GB: Swap
10GB: "/"
The rest is a logical volume: /Content


*Note, there is also a 40GB IDE drive for backup purposes
*Note, all drives are formatted as ext3

Any assistance would be much appriciated as I have been trying to get this webserver working for a long time now.

Thank You,
Max
