Message-ID: <20030309233502.GC1899@bubba.toscano.org> Mail-Followup-To: freebsd-questions@freebsd.org Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Disposition: inline Content-Transfer-Encoding: 8bit X-Unexpected: The Spanish Inquisition User-Agent: Mutt/1.5.3i Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG A couple days ago, I asked on the -hackers list about a problem I was having with Vinum and my Promise-based controllers. Søren replied with how to do this by using atacontrol to build the volume. No Vinum seems to be required. I thought Vinum was FreeBSD's RAID system. If you wanted to do software RAID with FreeBSD, you needed to use Vinum. Now I find this out. Does that ATA subsystem have RAID support built in? (Since atacontrol just seems to control the ATA devices...) If this is so, what's the use of Vinum? When should I use one vs the other? How do Vinum and the ATA subsystem's RAID relate?
