Centos – How to determine if a CentOS system is Raid-1

su - 
yum install gcc-c++ openssl-devel
cd /usr/local/src
wget http://nodejs.org/dist/node-latest.tar.gz
tar zxvf node-latest.tar.gz
(cd into extracted folder: ex "cd node-v0.10.3")
./configure
make
make install

Note that this requires Python 2.6+ to use ./configure above. You can modify the "configure" file to point to python2.7 in line 1 if necessary.

To create an RPM package, you can use FPM:

# wget http://nodejs.org/dist/node-latest.tar.gz
# tar zxvf node-latest.tar.gz
(cd into extracted folder: ex "cd node-v0.10.3")
# ./configure --prefix=/usr/
# make
# mkdir /tmp/nodejs
# make install DESTDIR=/tmp/nodejs/
# tree -L 3 /tmp/nodejs/
/tmp/nodejs/
└── usr
    ├── bin
    │   ├── node
    │   ├── node-waf
    │   └── npm -> ../lib/node_modules/npm/bin/npm-cli.js
    ├── include
    │   └── node
    ├── lib
    │   ├── dtrace
    │   ├── node
    │   └── node_modules
    └── share
        └── man

Now make the nodejs package:

# fpm -s dir -t rpm -n nodejs -v 0.8.18 -C /tmp/nodejs/ usr/bin usr/lib

Then install and check the version:

# rpm -ivh nodejs-0.8.18-1.x86_64.rpm

# /usr/bin/node --version

What you have is evidently not hardware RAID but software RAID with a BIOS interface, often called fakeRAID. The main job of putting the disks in an array is done by the Windows driver. Related reading: How do I differentiate “fake RAID” from real RAID?

There are two advantages to hardware RAID over software RAID: it's independent of the operating system (which is only useful if you dual-boot), and it can perform better in some configurations (essentially those that require a cross-drive checksum, which is not the case of RAID-1). Software RAID has the advantage of being independent of the hardware (you can take your disks out and plug them into another machine running the same OS) and tends to come with better tools.

So, forget about your motherboard's fake RAID and use Linux's software RAID. The main tool you'll need to use is mdadm. Create a RAID-1 volume encompassing the two disks, then create partitions on that volume. Something like:

mdadm --create /dev/md0 -l 1 -n 2 /dev/sda /dev/sdb
fdisk /dev/md0
