raidtab file
# Edit this file to the configuration that you want. The md# is not relevant
# as to what type of raid you are running. It is displayed here strictly for
# configuration information. The number of disks can also be changed for each
# raid type except raid 4,5 require 3 disks at a minimum. Spare disks can be
# added to any raid type except raid0.
#
# For IDE controllers it is highly recommended that each disk be installed on
# it's own controller due to performance issues although it is not required.
#
# Be sure that you have used cfdisk and changed the type of your disk partition
# to Linux raid autodetect [type] 'fd' before formatting and enabling raid.

# RAID0 setup with two disks:
# Striped for better performance, all drives must always be active.
