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

Look at the software-raid FAQ for more details. http://tldp.org/HOWTO/Software-RAID-HOWTO.html -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!
turn off the bios raid and use md to do the software raid because that's all you are doing. remove the vendors fake raid drivers from the process and enjoy a good raid experience..:) Patricia Bittencourt wrote:> Hi all, > > I?m trying to create a RAID1 on a machine.
