You can, of course, create the software raid.

Check out the link about how to create RAID array:

You can use RAID by software. Which linux distribution will you use?

The easiest way to do it is during the installation. See the installation guide for your distribution.

Basically, you need to configure partitions in the disks as "software raid", after that, you create the raid devices.

If you want to do after the installation is more complicated, but you still need to see the software-raid howto to know how to verify the status of the software raid devices.

Hi,

1.First of all, run fdisk and change partition type from linux LVM to linux raid auto 0xfd.
2.Then create a file /etc/raidtab , use man raidtab for helping u about creating it.
3.run mkdraid /dev/md0
4.mke2fs -j -b 4096 -R stride=x /dev/md0, where (x= chunck size/blocksize in k, could be 16 ...)
5.add a line for it in /etc/fstab

Also to be sure from the construction of raid: cat /proc/mdstat
