(Re)Install with RAID

Hello,

I have a SuSE 11.2 installation with a linux software RAID.

My installation is possibly corrupted. Now I want to do a full reinstall. But will I lose my RAID settings in the process and loss data. It is a RAID 0 config.

I do have the possibility to make it a hardware RAID but I know I will lose the data for sure.

I hope you all can help.

Why do you think that your installation is corrupted? May be, you can repair it.

It’s a long story.

I have problems with my computer after i did a HW-update (2 drives, 2 fans). It just keep crashing at random. If I can boot a OS Linux crashes within 2 minutes. If I start windows XP 32BIT (SuSE 64). Takes about 8 hours to crash.

It alsow will crash in bios and pre-boot or in GRUP.

My reseller tels me it’s Linux. I don’t believe them. And I want to prove them wrong by doing a full reinstall.

I know for it’s not the mainbord. It was send to ASUS and they didn’t found any thing!

If you can tell me someting else thats the problem please let me know.

Bad memory run the memory check on the install media.

Also are the two drives identical makes and models. You can have timing issues if they are not matched running RAID 0.

And do you really need RAID 0? Lose either drive and lose everything. Are you running RAID with Windows? Is this BIOS (Fake) RAID? You may need special drivers.

  1. Memory check is oke. There where no problems.

  2. The two drives are identical. Even made in the same hour.

  3. Well I use it to store my movies. There is no critical data on the drives but I have it for the big disks and I put the speed over safety(JBOD). I don’t have the raid in windows. But if I remove the drives it still crashes.
    It’s the software raid you can setup in YAST. The fake nForce RAID didn’t work in SuSE.

I installed Windows because my reseller doesn’t accept computer without Windows.

ok Still sounds like a hardware problem since Windows also fails.
If it were me I’d check for bad sectors with a lolevel disk scan. (get from drive maker)

If the drives are ok then a reinstall should not change anything. But like always you should backup important data before doing a fundamental change to the system.

It would be a good idea to run the memory check program repeatedly for some time. I still feel that it is related to memory.

I know it’s not the drives! While my MB was with ASUS I used an old bord/cpu/gpu and memory. And I didn’t had a problem.

I had run the memory test for about 4 hours and still no problem. Only the CPU is left. But that is more a hardware issue.

But the main question remains. If I format the Linux install drive and reinstall. I will not lose the data in the Linux software RAID? I don’t have SuSE installed on a RAID! I only use the RAID for storage of movies.

UPDATE:

I am running a memtest86 at the moment. If I let the program probe the memsize it’s about 3GB and if I use the BIOS it’s 4GB (as I have installed).
I remember Windows only shows 3GB but I remember this was/is a BUG in windows. So I didn’t had any attention for it.

D.

If you have installed 4GB, it should show that. Otherwise, there is something wrong. Do you have compatibility issues with different types of memory you purchased?

Also 32 bit os will only use 3 gig. 1 Gig is virtual memory reserved for the OS.

The memory is same make, same model, same bash.

I am still runing the memtest. Hope this wil bring someting up.

If I run the firmware test it crashes when the CPU test is at 100% pc crashes!

This is not a good sign. Anyway, such an issue will not get resolved if you re-install the OS.

I know this is the case. But I just want to prove them wrong.

Last night I was able to do the firmware check. I wasn’t able to save the results but I made a two pictures of the outcome.

They are BIG.

Now the system is corrupted. It will not start KDE. Updating or repairing the system isn’t working!

So I have to do a reinstall. But I still don’t know if the Raid will be lost! This is about 3 TB of data and a backup is not an option!

I hope I will get the right answer soon. It’s a RAID setup in yast. So it is not a fake or HW raid.

Then why raid0 ??

Raid 0 is just about the most dangerous way to store data. The least little thing goes wrong and you lose ALL your data.You should never ever run a RAID 0 configuration without a backup plan.

I use a RAID 0 for the extra storage. On the RAID drive I only have files of 8 GB or more. So with 2 drives in RAID 0 I get more storage then 2 single drives.

BTW It isn’t a big problem if I lose the data but more a shame so I rather don’t.

Sorry your math does not add up. You do get more on a single partition but the total bytes are the same. You could do the same thing with LVM and extend storage just by adding more drives with out the added danger of RAID 0. If the RAID 0 array goes south there is no way to recover.
