=====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.
