Dear All,
I just got a new server with the following specifications: motherboard : Intel S5500BC CPU : Xeon Quad Core 2.6Ghz RAM : 8GB HDD : 4 x 2TB SATA with configured raid 10 using raid embedded server.
The problem is the centos installer can't detect raid virtual disk. I can't find any log error with the following error messages during installation process:
Disks sda, sdb, sdc, sdd contain BIOS RAID metadata but are not part of any recognized BIOS RAID sets.
I'm already use search engine to find the information regarding to this issue, but I can't find the solutions for CentOS.
Thanks in advance

Simply Intel fake RAID. See

Either get a real RAID controller which does hardware RAID or use CentOS's software raid function.

+1. For Linux/CentOS/mdadm RAID 10 use "far" setting to get better (2x ??) read speed on mirroring.
