Hi:
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.
You have probably already seen all the other posts ... however I want to make sure everybody understands...
The RAID that is built onto the motherboards on almost all these chipsets _IS_NOT_HARDWARE_RAID_ ... any more than a win Modem is a real modem.
The RAID really is just software raid _WITH_A_PROPRIETARY_DRIVER_ .
The proprietary nature of that driver makes it much less stable than linux software raid.
So, as others have mentioned, buy a REAL hardware RAID card ... like vmware ... or use software RAID.
I'm sure you meant 3ware here. One of those days! ;-)
Also, as others have mentioned, please search for "fake raid" or "fraid" on google for more information.
Thanks, Johnny Hughes
