=====SME 8=====
 +
Here is a summary of what has changed:
 +
 +
- There is no longer a noraid boot option
 +
- New boot option raid=[none,0,1,5,6]
 +
- There is no longer a nospare boot option.
 +
- New boot option spares=[0-(disks-2)]
 +
- New boot option drives=[hda,sda,xvda,...]
 +
 +
The installer without anything being passed should behave identically for disks
 +
< 10 with the exception that it won't include any device that is housed on a
 +
drive that needs the usb-storage or spb2 module.
 +
 +
If you want to include drives that are on USB or firewire you must use the
 +
drives= option and specify all drives (not just the usb/firewire drives) that
 +
you want to use.
 +
 +
If you don't want to use raid at all specify raid=0 or raid=none (they are
 +
identical, 0 means none).
 +
 +
If you don't want a spare you should use the spares= option and specify a value
 +
of 0.  By default 1 spare will be added for disks > 3.  Another spare drive
 +
will be added for every additional 7 drives you add (10, 17, ...).
 +
 +
If you specify a raid level but don't have enough drives it will fall back to
 +
the next highest raid level (ex. 5 drives, 2 spares, raid 6 will fail back to
 +
raid 5 as 5-2=3 useable drives).
 +
 +
This will need extensive testing before 8.0 goes final.  There are lots of
 +
possibilities and combinations.  It should allow those with a control complex
 +
to setup their raid/space the way they want to.
