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.

Installing OpenSuse 11.0 on RAID Array

Asked by Ravelstaff in SuSE Linux, Linux Setup, Storage Technology

Tags: , , , , ,

I want to install OpenSuse 11.0 on a RAID array for redundancy. I have four 750GB SATA drives connected to a HighPoint RocketRAID 2300 series RAID controller. HighPoint's web site for this model controller shows that it is supported up to OpenSuse 10.3 (see http://www.highpoint-tech.com/USA/bios_rr2300.htm).

How do I get the OpenSuse installer to recognize the RAID array set up with the RockerRAID BIOS utility? At present the array is created in the BIOS utility but the OS installer only sees the four individual drives and it then suggests the default partitioning scheme on the first drive only. I understand that I probably need to load a RAID driver for Suse but I don't know how to do this given I do not have a floppy drive available on the server, nor do I have a precompiled driver for Suse11.0.

HighPoint provides a generic open source driver that's been tested with kernel 2.6.25. which is what shipped with OS11.0 if I am not mistaken. The README that comes with the opensource driver download talks about compiling the driver module for the kernel but I cannot do this during the installation can I?

Unless I change my strategy entirely and add one more drive to install Suse11.0 on and then compile the RAID driver afterward so I can use it later but this means if my primary Suse drive fails I have to redo practically everything to get the machine up and running again which kind of defeats the purpose of using a RAID array methinks.

1. Does anybody have any ideas about how to get the RAID array going for the installer to use it as a single installation destination?
2. Can I install the operating system on a RAID array, or should I rather keep it on a dedicated drive, and only use the RAID array to store more important data on? If so, in case of a drive failure, the way I understand it is that my data will be OK but I'll have to rebuild the operating system and mount the data array again when it's done?
3. Is there a better way to do this?
