31.1Sagc# Structure of this file:
41.1Sagc#
51.1Sagc# + an extent is a straight (offset, length) pair of a file or device
61.1Sagc#   it's the lowest common storage denominator
71.1Sagc#   at least one is needed
81.1Sagc# + a device is made up of one or more extents or other devices
91.1Sagc#   devices can be added in a hierachical manner, to enhance resilience
101.1Sagc# + in this example, no device definitions are necessary, as the target
111.1Sagc#   will just use a simple extent for persistent storage
121.1Sagc# + a target is made up of 1 or more devices
131.1Sagc# The code does not support RAID1 recovery at present
141.1Sagc
151.1Sagc# Simple file showing 1 extent, mapped straight into 1 target
