“1 Preliminary Note

“In this tutorial I’m using a CentOS 5.3 system with two hard
drives, /dev/sda and /dev/sdb which are identical in size. /dev/sdb
is currently unused, and /dev/sda has the following partitions:

* /dev/sda1: /boot partition, ext3;
* /dev/sda2: swap;
* /dev/sda3: / partition, ext3

“In the end I want to have the following situation:

* /dev/md0 (made up of /dev/sda1 and /dev/sdb1): /boot
partition, ext3;
* /dev/md1 (made up of /dev/sda2 and /dev/sdb2): swap;
* /dev/md2 (made up of /dev/sda3 and /dev/sdb3): / partition,
ext3″
