RAID not working with M5A99X

Post by Zilacon » 2016/06/21 20:25:50

I have been trying to figure this out forever and even googled until im blue in the face with no success so here I am asking for help.

I saw there is a similar post about my issue with a gigabyte board here: viewtopic.php?t=7114
But it was not solved. The motherboard has a raid controller on it so there should be no need to spend money on a RAID card for such a small setup.

I have 4 hard drives all 1TB Seagates. I set them up in RAID 0 and the linux installation says it is not part of any recognized bios raid sets. Now the strange thing about this is, it worked before. I had 2 hard drives in the system before in RAID 0 and it recognized them and installed them no problems. However one of the disks eventually died due to heavy load and i decided to go to 4 HDD's like my main system which has never had a issue in 6 years with its 4 HDD's. And then when i did this, this problem started.

Any solutions to this would be great. I have 4 identical systems using the same cpu, motherboard, memory, graphics cards, even power supplies are the same. The main server i spoke about is running 4 WD Caviar Blacks in RAID 0 on Centos 6 with no issues for many years. This system im having problems with as well had no issues running Centos 6 before the HDD upgrade.

System Specs:
ASUS M5A99X Motherboard
AMD FX-8350 CPU
Patriot VIPER 8GB X 4 (32GB)
4x WD or Seagate HDD's in Raid 0
Corsair RM650 Power Supply

Thank you to anyone that can help me solve this problem!

Don't use BIOS fakeraid. Use AHCI mode on the controller and use Linux's md RAID.

I have used BIOS raid for years with no problems. I have tried linux's "Software Raid" and the performance was 1/4th of the speed i got with my BIOS raid. I am using the Raid 0 array for high demand read/write use. I tried having just 2 drives and the stress on them killed them. However the 4 drive raid ive had going for 6 years strong has not had a single issue.

BIOS "FakeRAID" is almost universally derided in the linux world.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
Use the FAQ Luke

I just want to know why it worked in the past but it does not work now.
And how to set it up the same way I did in the past.

Thats all I want.

If performance was so slow, you probably didn't have it set up properly. BIOS RAID isn't so different: it uses a slow embedded processor, instead of using the main CPU's much, much faster processor.
