# Short-Description: Multiple Device RAID
|
|
# Description: Start MD RAID
|
|
# RAID devices are virtual devices created from two or more real block devices.
|
|
# This allows multiple devices (typically disk drives or partitions there-of)
|
|
# to be combined into a single device to hold (for example) a single filesystem.
|
|
# Some RAID levels include redundancy and so can survive some degree of device failure.
|
|
