The framework is intentionally designed to support only the basic functionality, as it will ultimately be used to support many RAID controllers. Theo explains, “the functionality supplied is also very basic, almost minimal. But this is done like this on purpose, since we believe that we could support this functionality on all RAID controllers in the same way, without special ‘but that controller is so different’ mindsets entering the picture. RAID management should (and can be) be no more complicated than ifconfig managing network interfaces.”

Can raidframe support RAID6?
You do know they’re talking about hardware RAID right? Besides, what’s RAID6? I that RAID5 plus mirroring? The heck with software RAID, just go hardware RAID. With the advent of SATA and 3Ware it’s gotten alot cheaper to setup reliable RAID systems.
Here’s a note of interest:

Actually, most hardware raid controllers on the market today are actually fake-raid. In those cases, software raid is the only way. True hardware raid controllers are still uncommon, and not that cheap either.
Linux’s libata guys maintain a list of raid controllers and whether they are fake or true raid, just google for it and you’ll see how the hardware manufacturers are playing customers for fools.
DragonFly BSD recommends 3ware.

Matt’s not looking to support RAID himself, OpenBSD is. That’s a difference, OpenBSD developers want to do RAID right.
It seems he have tried cards from one vendor and liked them!
The MegaRAID cards are nice, they use the same driver for all cards, you can move disks from an old Fast SCSI controller to a new U320 PCI-e controller and it just works. Besides LSI have supported drivers and mgmt program for FreeBSD. (3ware and Adaptec also have this).
The problem at present with the MegaRAIDs is that they don’t support arrays over 2TB. For such arrays 3ware is a better choice. For speed (SCSI disks) the MegaRAID 320-2e is the king!
that someone did this right.
BRAVO OpenBSD!
LSI Logic acquired the MegaRAID business from AMI in mid 2001. Isn’t it time to update the ami man page in 3.8
I know OpenBSD is often seen as old and behind but this is ridiculous!

Probably. Where is your patch?
So how do you make one of these “patches”? Any simple, easy-to-digest “How-To” docs on the proper incantations of diff (or whatever is used) to create a patch?

OpenBSD servers rock!!
🙂
I have had much longer uptime on Linux. So I guess it rocks also
high uptime just means you’re not patching properly.
Being this a very nice feature to have,I proposed to port it to FreeBSD: http://lists.freebsd.org/pipermail/freebsd-current/2005-September/0…
