I tried to install Centos 6.2 on raid 5 (4 x 4 TB) HP Proliant DL 160 Gen 8. First of all Centos don’t detect raid driver on installation. You have to find b120i raid driver for Centos 6.x OS. You can find my preview Post.
During boot of the Centos 6.x DVD, you need to choose Rescue Mode option with TAB button. add below string end of the line,
… linux dd blacklist=ahci
Please show the raid driver on related window in Centos boots.
After that you will see shell command screen. On this screen
command will be used like…
$ parted /dev/sdb
Create a GPT partiton label
(parted) mklabel gpt
you should create partitions what you need with mkpart…
for boot partition (512MB-0MB = 512MB)
(parted) mkpart boot 0.00MB 512.00MB
for swap area (10GB-512MB = 9.5 GB)
(parted) mkpart swap 512.00MB 10.00GB
for root partition (50GB-10GB = 40 GB)
(parted) mkpart root 10.00GB 50.00GB
for backup, remaining empty space (remaining space-50MB = ??)
(parted) mkpart backup 50.00GB -0
to review partition table

After created partitions, You must format the backup partition. Centos can not format this partition because it is big size.
$ mkfs.ext4 /dev/sdb4
After reboot you need to boot Centos 6.x installation DVD with raid driver options. (linux dd blacklist=ahci)
Please keep going on normal installation steps until partitions setting.
Please select customer partition options and don’t touch sdb4 partition area. After finish installation, you can use the sdb4 partition like below,
# mkdir /backup
# mount /dev/sdb4 /backup
Don’t forget to adding fstab to don’t mount after restart
