# Structure of this file:
#
# an extent is a straight (offset, length) pair of a file or device
# it's the lowest common storage denominator
# at least one is needed
# a device is made up of one or more extents or other devices
# devices can be added in a hierachical manner, to enhance resilience
# in this example, no device definitions are necessary, as the target
# will just use a simple extent for persistent storage
# a target is made up of 1 or more devices
# The code does not support RAID1 recovery at present

# Simple file showing 1 extent, mapped straight into 1 target

# extent file or device start length
extent0 /r5/iscsi-target0 0 1800MB

# target flags storage netmask
target0 rw extent0 0.0.0.0/0
