Raider is a tool to automate linux software raid conversion.
It is able to convert a single linux system disk in to a software raid 1, 4, 5, 6 or 10 system in a two-pass simple command.

  Raider is a bash shell script, that deals with specific oddities of several linux distros (Ubuntu, Debian, Arch, Mandriva, Mageia, openSuSE, Fedora, Centos, PCLinuxOS, Linux Mint, Scientific Linux, Gentoo, Slackware... - see README) and uses linux software raid (mdadm) ( and ) to execute the conversion.

  Quick How-To
Run help first:
# raider --help

Conversion to RAID 1
  1. Add a new empty disk with the same size of the original.
  2. Turn on the system, login as root in text mode, or in a terminal window.
  3. Run this command (STEP 1):
    # raider -R1
  4. Let the program run and in the end, shutdown the system, swap the disks, and turn on the system again.
  5. Login as root again and run this command (STEP 2):
    # raider --run
  6. This will sync both disks, and in the end we will have a raid 1 system working.
If making a conversion to other raid type, the procedure is the same, but you have to add more disks.
In step 4, you have to swap the first disk with the disk in the last slot position.
