I've tried to install centos 4.3 in a raid array, setuped on bios as mode "Adaptec". The chip is ICH7R but centos always sees 2 drives instead of the array that I create. I've contacted Supermicro support and they gave me this link ftp://ftp.supermicro.com/driver/SATA/Adaptec_ICH7R/Linux/Redhat/ , but the disk drivers I tried to use with centos 4.3 did not work, saying that the disk did not containt appropriate drivers for the hardware.
Have anyone here had similar problems? does centos 4.4 solves this issue?
I really need to install centos as an array... and as hardware RAID and not software RAID.
Then you should have purchased a hardware RAID card. What comes on the motherboard is in fact software RAID, it just uses a proprietary driver to do all the work. (Search the net for Fake RAID of FRAID).
If you can't purchase something like a 3ware card, your best bet is to use the software RAID that comes with Linux. Otherwise you're just asking for a world of hurt.
