[CentOS] Re: RAID1 building via hardware

Patricia Bittencourt spake the following on 1/30/2007 8:27 AM:

Hi all,

   I´m trying to create a RAID1 on a machine. I´ve already

configurated BIOS (mother board, Intel, S500VSA SATA) so as to build RAID1 via hardware. However on CentOS Installer, when I reach "disk setup" screen, it shows up 2 devices (/dev/sda and /dev/sdb).

   Is this right (both devices being showed)?

   How should I proceed on this moment? If I create the partitions

on sda, sdb will be identical?? There is no away to assure this on the installation, so that the doubt came to my mind...

thanks in advance, Patricia

It sounds as though your boards raid is "fakeraid". http://linuxmafia.com/faq/Hardware/sata.html

Linux will see the base controller, as the raid is not true hardware raid. Look at the software-raid FAQ for more details. http://tldp.org/HOWTO/Software-RAID-HOWTO.html
