Installation:

Copy swraid.device To DEVS:

Usage:

Create a file ENVARC:swraid.device.xml using either PrefsObjectEditor or
NotePad. An "example" configuration file is provided in the archive.

The device supports two types of RAID:
 - mirror (reads are striped across disks)
 - stripe (both reads and writes are striped across disks)

There is a hardcoded limit of 32 units in a RAID array.

"mirror":

Next you should create identical (same position, size, device name, etc.)
partitions on all harddrives (make sure that AutoMount is disabled).

Mount the partitions using:
Mounter device=swraid.device unit=<swraid unit> <device name:>

F.e.:
Mounter device=swraid.device unit=0 RAID0:

Now the partitions should be visible on WB and you can do a "Quick Format"
on each and one of them.

"stripe":

If you use striping either use DOSDrivers (MediaToolBox can be used to output
these, just remember to multiply BlocksPerTrack by the amount of disks in your
RAID), or mount the harddrive first using a dummy mountlist such as the RAID0
that's included in the archive and then either format the disk from WB or use
MediaToolBox to setup an RDB on the disk (select "swraid.device" in the devices
list).

Bugs:

This is an ALPHA release that has seen little testing so there may be some.
Don't use for important data for now. You have been warned.
