How To Create Software Raid 0/1 From OS Install.

RAID 0 (or) Striping

RAID 0 is ideal for non-critical storage of data that have to be read/written at a high speed, such as on an image retouching or video editing station.

RAID 1 (or) Mirroring

Data are stored twice by writing them to both the data drive (or set of data drives) and a mirror drive (or set of drives). If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continuous operation. You need at least 2 drives for a RAID 1 array.

  • Format all disk.

  • From the first disk put 1Gb in /boot

  • leave unformatted the same number of GB on each partition and press create software RAID (md)

  • Select the “Create software RAID (“MD”)” button to open the creation dialog. The server installer supports creating devices with RAID levels 0, 1→ select all disk → press create.

  • From md0 free space create the partitions ass needed or required.

  • Press done and continue the installation.
